General With what types of classes can ODYSSEY be used?

ODYSSEY is widely used in first-year college courses as well as high school science classes. Since diverse content is included with the program, regular chemistry students as well as honors and AP/IB students will find suitable material. Many middle school teachers, high school Physical Science teachers, etc. have also benefitted from using ODYSSEY's powerful visualization technology with their classes.

General Does the program replace conventional textbooks?

ODYSSEY provides instructors with a powerful tool to introduce and enforce many of the molecular concepts of chemistry. For the most part, this is accomplished through visualization exercises and laboratory-style experiments. Effectively, ODYSSEY does not replace, but complement textbooks. The program also complements other teaching software where the emphasis is more on repetitive problem drills.

General What is the difference between ODYSSEY and molecular visualizers?

Molecular visualizers such as "Jmol," "Chime," and "Rasmol" are quite popular. The functionality of these visualizers is a small subset of that of ODYSSEY and essentially amounts to two core features:

Unlike molecular visualizers, ODYSSEY is a full-fledged simulation and teaching tool. Unique features include the following:

General How is the program different from Flash-based simulation software?

ODYSSEY as well as many Flash animations and Java applets purport to employ a "simulation" approach. However, despite the same label, the two types of software have little in common:

Versions Is ODYSSEY available in different versions?

Similar to introductory textbooks, ODYSSEY is available as a Student Edition as well as an annotated Instructor's Edition. The functionality of the Student Edition is a comprehensive subset of that of the Instructor's Edition. The Student Edition does not include the Answer Key for the more than 40 worksheets.

Versions Under what operating systems will ODYSSEY run?

ODYSSEY is available for Windows and the Mac OS X operating system. The installers for the two platforms are on the same disk, but there are two separate disks for the Student and Instructor's Editions.

Versions Is ODYSSEY available for Linux?

No, ODYSSEY is not available for Linux.

Versions Is ODYSSEY offered for languages other than English?

ODYSSEY is currently available in English (Windows/Macintosh), Spanish (Windows only), and Japanese (Windows/Macintosh).

Requirements Will the program run under any Windows operating system?

ODYSSEY requires Windows Vista, Windows XP, or Windows 2000. The program will not run under older operating systems, such as Windows 98 or Windows ME.

Requirements Will the program run on any Macintosh?

ODYSSEY requires Mac OS X 10.4.6 Tiger. Both the new generation of Intel chips and the older generation of PowerPC chips are supported. However, the program will not run under older releases of the Macintosh operating system.

Requirements Does ODYSSEY require an expensive computer to run on?

No, ODYSSEY will successfully run on essentially any computer that has been purchased within the last ~3 years. The minimum requirement is a clock speed of ~2 GHz (Pentium 4 / Celeron, both running under Windows) or ~1 GHz (Pentium M / Core Duo / various AMD chips, all running under Windows; Core Duo / PowerPC, both running under MacOS X).

Requirements Will ODYSSEY run on machines below the minimum requirements, albeit a little bit more slowly?

On computers that don't meet the minimum requirements, ODYSSEY will run so slowly that dynamic simulations are basically not feasible. Since such simulations are central to the program, ODYSSEY will not be functional.

Requirements Does the program require online connectivity?

No, ODYSSEY is a locally running application that does not access the Internet. The only exception is the activation step if you purchase the program with an activation code: In that case, the program briefly accesses the Internet while installing.

Requirements Does the program run on tablet PC's?

Yes, ODYSSEY runs on Windows tablet computers (release 1.3 and up).

Requirements Can the Windows version be run on a Macintosh that has Boot Camp and Windows XP installed?

Yes, ODYSSEY can be run in the Windows mode of a Boot Camp-configured Macintosh without any loss of performance. Note that you need valid and independent licenses both for the operating system (Windows XP) and ODYSSEY.

Requirements Can the Windows version be run under Mac OS X using Parallels?

While it is possible to run the Windows version of ODYSSEY on a Macintosh using Parallels, this is not recommended because of a significant degradation in performance.

Requirements Can the Windows version be run on a Macintosh using Virtual PC?

No, ODYSSEY cannot be run on a Macintosh computer using Virtual PC.

Requirements I use an alternate browser, such as Firefox. Is Internet Explorer still required for the Windows version?

Yes, ODYSSEY's Windows version requires that Internet Explorer (version 6 or later) is installed. This applies even if you never use the browser by itself.

Requirements Does ODYSSEY work with Internet Explorer 7?

Yes, starting with release 2.0.1, the Windows version of ODYSSEY works with Microsoft's new Internet Explorer 7. Older releases do not work with IE 7.

Requirements Doesn't the fact that the program uses a web browser mean that it is an online application?

No, except for a single situation, ODYSSEY is a locally running application that does not access the Internet. In other words, Internet Explorer/Safari is used as local content browser rather than a "web" browser.

The only exception is the activation step if you purchase the program with an activation code: The program accesses the Internet just once (namely on installation) in order to activate the program.

Requirements What are the graphics card requirements?

There are no specific requirements. On Windows machines, you can use the Reduced Graphics for Slower Machines option in Tools Preferences if the graphics performance seems unsatisfactory.

Requirements Can the program be run in 8 bit color mode?

No, ODYSSEY does not support 8 bit color mode ( = 256 Colors).

Installation How do I install the Windows version using an activation code?

The following steps require that you are connected to the Internet and that your Firewall is not so superstrong that it interferes with basically any communication with the outside world:

Installation What do I do if I purchased ODYSSEY with an activation code and my online activation attempts are failing?

Use the offline activation procedure. See FAQ "How do I install using an activation code if I don't have Internet access?"

Installation How do I install using an activation code if I don't have Internet access?

If you purchased ODYSSEY with an activation code and your computer does not have Internet access (or if you have a particularly strong Firewall that foiled your activation attempts), you need to activate offline. The following steps describe the required steps for Windows—the procedure for the Macintosh is analogous:

Installation How do I install using an individual USB key?

The USB key version of ODYSSEY allows for the software to be installed on multiple machines; it can then be accessed wherever the USB key is plugged in (note that simultaneous use on multiple machines requires a USB network license instead). The following steps describe the required steps for Windows—the procedure for the Macintosh is analogous:

Installation How do I install using a Network License?

The following document provides network installation directions:

Installation What do I do if the Windows program crashes immediately after installation?

Try to lower the "Graphics Hardware Acceleration" if ODYSSEY crashes immediately after installation:

Installation How do I uninstall the Windows version?

To uninstall the Windows version of ODYSSEY:

If the Uninstall shortcut in the ODYSSEY program group is not available:

User Interface Can I change the size of the text, properties, and plot areas?

The user can control the screen layout by changing the size of the window tiles (release 2.0 and up):

Vertical separators (between Build/Cell/Plots area, Model area, and Text area):

Horizontal separator (between Model area and Properties area):

User Interface How do I change the size of the text?

In the Windows version, the text size can be altered independent of the screen resolution. If you have a mouse with a scrollwheel, check whether the following works:

ODYSSEY will remember the new setting the next time you start the program. — While the technique above does not work on all computers, the following will always work on Windows machines:

In the Macintosh version, you must change the screen resolution in order to change the text size:

User Interface Can I change the fonts?

The fonts of the main text panel as well as of other text strings in the program cannot be changed.

User Interface Can I use an icon tool bar similar to the one seen in SPARTAN?

To display a toolbar with icons for the Select modes and the various Build operations including Minimize:

Note: In the Windows version, the menu item is accessible from any page, including the initial page. In the Macintosh version, a page with a molecular model must be open.

User Interface Does clicking on the Refresh/Reload icon only affect the currently displayed model or page?

No, while clicking on the refresh icon takes you back to the subpage that you were on, it refreshes all models and all subpages of the current experiment. (Experiments in other tabs are unaffected by a refresh.)

In the Macintosh version, a Reload option is available in the shortcut (right-click) menu when the cursor is within the text area. However, the effect of this reload is limited: It only refreshes the HTML of the current subpage, i.e., it does not refresh the molecular model and it does not refresh other subpages.

User Interface Can I suppress the text panels of Experiment/Stockroom pages?

To temporarily hide the text panel of the current page:

To permanently hide the text panels of all pages (Instructor's Edition only):

User Interface Can I put the program into true Full Screen Mode, similar to PowerPoint?

The Windows version of ODYSSEY can be put into presentation-style full screen mode:

To exit full screen mode:
User Interface What do the colors in the Periodic Table stand for?

The Periodic Table (in the Tools menu) can be displayed with the following color overlays:

User Interface Where do I declare the charge when I build an ion with the Atomic Model Kit?

ODYSSEY evaluates built structures using common valence rules and assigns charges accordingly. A tetrahedrally coordinated nitrogen atom, for example, is "recognized" as carrying a single positive charge. An explicit declaration of the charge is not required.

If your built molecule is not in the desired charge state, try to find the molecule (or a similar one) in the program's Molecular Stockroom—because of custom settings it may be in exactly the charge state that you are after.

Plotting and Printing How do I avoid that datapoints are covered up by a plot's caption?

To move the caption of plots (e.g., in order to expose datapoints "hidden" behind the caption):

Plotting and Printing How do I print snapshots of molecular models?

To print a molecular model if no plot is displayed:

To print a molecular model while plots are displayed at the same time:

Plotting and Printing How do I print a plot?
Plotting and Printing How do I print the text panel?

Printing of the HTML-formatted text is different for the two versions:

Plotting and Printing How do I print the properties table?

In the Windows version, use the computer's screen-capture facility (many machines have a special "Print Screen" key):

In the Macintosh version, the "Properties" table can be printed directly from ODYSSEY:

Plotting and Printing How do I print the entire screen?
Plotting and Printing How can I suppress the Windows "Blocked Content" message bar when printing PDF-formatted worksheets?
Classroom Use Can ODYSSEY be used with interactive whiteboards?

Yes, ODYSSEY is well suited for classrooms that are equipped with Smartboards or other interactive whiteboards.

Classroom Use Can I use the program with PowerPoint?

ODYSSEY can be seamlessly hyperlinked into PowerPoint. You have the choice among the following possibilities:

In each case all features of the ODYSSEY interface (simulation control icons, etc.) are fully available after following the hyperlink in your PowerPoint presentation. See the following items for detailed instructions on how to create hyperlinks.

General Note: When you run PowerPoint and use ODYSSEY hyperlinks, be sure to close ODYSSEY before moving back to PowerPoint (or you will soon run out of compute power as each new hyperlink will open ODYSSEY again).

Classroom Use How do I hyperlink an individual molecular model?
Classroom Use How do I hyperlink the program's initial page?

If you link to ODYSSEY's initial page, you can access any experiment and/or model via that hyperlink:

Clicking on the object in the PowerPoint slide (when in presentation mode) will now always take you to the initial page of ODYSSEY. You can go wherever you wish from there.

Classroom Use How do I hyperlink an experiment or a stockroom page?

ODYSSEY experiments and stockroom pages can be hyperlinked into PowerPoint presentations. Note that the hyperlink must refer to a .odyssey or .splink file in its original location in the ODYSSEY folder—a copy of the file somewhere else will not do.

Classroom Use How do I suppress the Windows security dialog when hyperlinking into PowerPoint?

To suppress the "Security Dialog" when hyperlinking into PowerPoint (all of the actions are required):

Classroom Use How do I incorporate animations (sequences of frames) into my classwork?

To incorporate ODYSSEY animations (dynamic sequences of frames) into lectures, PowerPoint presentations, laboratory experiments, and homework assignments:

Since ODYSSEY is organized around the paradigm of live, interactive simulations, corresponding "movies" cannot be saved. (Please note that the license agreement explicitly prohibits capturing of dynamic ODYSSEY simulations by any means.)

Classroom Use Are my students prevented from building "nonsense" molecules?

Generalizing the approach of conventional plastic model kits, ODYSSEY provides building blocks and tools for the construction of a great variety of molecules and systems. While some of the tools imply certain constraints (e.g., the building block "tetrahedral" carbon obviously implies that there is a bias towards 4 single bonds around a carbon atom—as opposed to either 3 single bonds or 5 single bonds), the student is, strictly speaking, not prevented from building chemical "nonsense" structures. Of course, the same is true for plastic model kits—and also for drawing Lewis structures on a piece of paper!

In essence, ODYSSEY empowers the student to learn chemical rules in an open-ended, active format. This approach is distinctly different from that of typical "drilling software" where the chemical intelligence has been programmed into a sequence of dialogs that leave the student with nothing but the memorization of rules.

Classroom Use How can I assess student work carried out with ODYSSEY?

ODYSSEY includes more than 40 different worksheets that are included as PDF files with every copy of the program. In the Instructor's Edition, the worksheets are also available as editable WORD files.

Assessment can be carried out in several different ways:

Molecular Visualization Can I depict lone pairs?

To display a schematic representation of lone pairs (where applicable):

Note: For models with "electronic surfaces," the visualization of lone pairs may not always be available.

Molecular Visualization Why can't I highlight the collisions of the sample of gas that I built?

The "Collisions" attribute (in the Model menu) is only available for samples whose density is not too high (this protects the computer from being overwhelmed by collision counting in higher density samples). A rule of thumb is that letting the pressure drop to less than ~10 atm (use Build Cell Gas) will make the "Collisions" attribute available.

Molecular Visualization Can I highlight the sequence of residues in proteins and nucleic acids?

Proteins and nucleic acids that contain explicit residue information (this includes models that have been built with ODYSSEY's Peptide or Nucleotide builder as well as PDB files from the Protein Data Bank) can be displayed as "Ribbon" models with a visual indicator for the sequence of residues:

Molecular Visualization Why do molecules of liquids and solids sometimes "disappear"?

In simulations of liquids or solids, you may notice that some molecules or atoms seem to leave the simulation cell, i.e., when close to one of the boundaries they often seem to be gone a few moments later. If you look carefully, however, you will also notice the opposite, namely "new" molecules (or atoms) that seem to enter the simulation cell.

What is going on? The explanation is that there really aren't any "boundaries" when ODYSSEY simulates a liquid or solid—despite the obvious presence of a simulation cell. What the program really uses is called Periodic Boundary Conditions: essentially, the simulation cell "wraps around" in each of the three dimensions. If, for example, a molecule leaves the simulation cell towards the right, the same molecule re-enters from the left! In effect, we have allowed the molecule to cross the system boundary while not losing anything—the system density remains perfectly constant.

The huge advantage of this approach is that there are no walls in the system that can interfere with the calculated bulk properties.

Molecular Visualization Why do some molecules at the simulation cell boundaries look "clipped"?

ODYSSEY generally employs "Periodic Boundary Conditions" when simulating liquids and solids (see FAQ "Why do molecules of liquids and solids sometimes disappear?"). By default, the visualization is such that any molecules that fall right on the boundaries are shown with some of their atoms still on one side, while the molecule's remaining atoms are already shown re-entering on the other side.

If desired, you can turn this type of clipping off so that the molecules always seem to "leave" and "re-enter" the simulation cell as complete entities rather than with clipped bonds:

Note that the clipping preference only affects the visualization of molecular systems—the underlying simulations are completely unaffected by the preference setting. Also note that some systems (such as liquid sulfur) have a fixed setting for the periodic boundary clipping that is not overriden by the preference setting.

Molecular Visualization Why do many models of liquids and solids contain one molecule that looks "different"?

For the purpose of highlighting, ODYSSEY often shows one (arbitrarily selected) molecule in a different model style. For liquids, for example, the highlighted molecule is typically shown Space Filling so as to give an idea of the true shape of the molecule. The "background" of other molecules, however, is typically shown in the Wireframe or Tube style so as not to clutter up the picture with an abundance of large spheres for each and every atom.

Molecular Visualization Can I show two models at the same time?

Comparing systems, situations, and scenarios is one of the most effective teaching techniques. ODYSSEY facilitates comparisons of molecular systems in several ways.

Molecular Visualization What can I do if the graphics performance is poor, particularly when using the "Space Filling" model style?

On Windows computers, you can try the following:

Molecular Visualization What can I do about unsatisfactory graphics performance when running on battery?

On Windows computers, you can try the following:

Physical Properties How do I measure physical properties?

To query the numerical values of physical properties:

Physical Properties How do I change the physical units?

To change the default settings:

Physical Properties Can I overwrite the "slider" limits in the property table?

Built-in limits for temperature, volume, and composition sliders can be overwritten by entering the property value as a numerical value:

Note: The limits of the corresponding slider are immediately updated to include the newly requested value.

Physical Properties How do I minimize the energy of a molecule?

To minimize the energy of any molecule or any other system in vacuum:

Note: Minimization of liquid and solid structures is not available.

Physical Properties How are the energies calculated?

For each molecular model, ODYSSEY calculates the energy of interaction between the atoms that are present, regardless of whether the sample is an isolated molecule or a bulk phase with many molecules. The "potential function" is very complicated—there are many hundreds of parameters for all the elements and valence states encountered in chemical compounds. At least conceptually, however, the potential function can be thought of containing the following main terms:

There are a few other terms, but essentially it is the sum of these energies that yields the total energy of a given system. Calculation of the derivatives of the total energy with respect to the coordinates of all the atoms yields the intermolecular forces that are at the heart of the algorithm that takes the system from one time step to the next. As the energy depends on the coordinates of all the atoms in the system, the calculation has to be repeated even if only a single atom moves.

Physical Properties How are enthalpies calculated?

In order to allow for an intuitive interpretation of the thermodynamic consequences of temperature and phase changes, ODYSSEY adopts a unique reference state for enthalpies. The displayed values (from empirical formulas that represent best fits of experimental data) are always relative to the elements in their standard states at 25°C. Note that this is different from what is implicit in many thermodynamic tables:

ODYSSEY abstains from working with varying reference states.

Physical Properties How are entropies calculated?

ODYSSEY displays standard entropies. The algorithm used depends on the complexity of the given system and involves certain combinations of analytical statistical thermodynamical theory and empirical formulas (with the latter representing best fits of experimental data).

Physical Properties How are free energies calculated?

In order to allow for an intuitive interpretation of the thermodynamic consequences of temperature and phase changes, ODYSSEY adopts a unique reference state for free energies. The displayed values (calculated from the underlying enthalpy and entropy data) are always relative to the elements in their standard states at 25°C. Note that this is different from what is implicit in many thermodynamic tables:

ODYSSEY abstains from working with varying reference states.

Physical Properties How are hydrogen bonds identified?

ODYSSEY identifies a hydrogen bond if an atom with an attached hydrogen is close to another atom and all of the following criteria are satisfied:

Physical Properties Do the calculated properties reproduce experimental data?

There is no blanket answer to the question. In many cases, there is qualitative agreement between calculated and experimentally measured properties. Particularly "trends" (such as variation with atomic mass, variation with dipole moment, or variation with temperature) are very often predicted correctly. Predictions that are quantitatively correct are rare as the program employs models that are computationally inexpensive and therefore imperfect.

While not very common, outright failures also occur. However, it should be kept in mind that the presence of failures and limitations is a defining characteristic of all models—not only scientific models, but also models anywhere else. The pedagogical value of models derives from their ability to be experimented with, not from being perfect replacements of the "real thing."

Physical Behavior Why do the vapor molecules of a given substance don't seem to move much faster than the liquid molecules?

In order to facilitate observations of a wide variety of systems, ODYSSEY autoscales the size of the simulation cell to the screen size regardless of the physical state of the substance. As gas phase simulation cells are typically much bigger than condensed phase simulation cells (see the Cell Dimensions displayed above the modeling area!), the net motion in the gas phase is in fact much faster than the net motion in the liquid phase.

In accordance with temperature, the molecular speeds themselves are also higher in the gas phase than in the liquid phase:

Physical Behavior Does ODYSSEY assume ideal gas behavior?

No, ODYSSEY never assumes ideal gas behavior. Gas molecules are always modeled as particles of finite volume that exhibit non-negligible interactions (if sufficiently close).

Nevertheless, ideal gas behavior will be observed in many situations, namely whenever the physical conditions happen to closely correspond to the assumptions that are implicit in the Ideal Gas Law.

Physical Behavior Can I simulate the liquid-vapor transition?

The liquid-vapor transition can easily be simulated for most liquids:

Physical Behavior Will gases condense on cooling?

Yes, given sufficient simulation time and a sufficiently low temperature, samples of gas will eventually show condensation. However, the condensation will happen via the formation of irregular molecular clusters rather than through the formation of a "neat" horizontal interface. The reason for this is the insignificance of gravitational forces in samples that are as small as those simulated by ODYSSEY (see FAQ "When I turn a partially filled simulation cell "upside down," why doesn't the liquid flow to the bottom?").

Physical Behavior When I turn a partially filled simulation cell "upside down," why doesn't the liquid flow to the bottom ?

The reason for this at first glance strange behavior is that gravity does not make a difference for molecular-sized samples. A number of very familar phenomena, however, crucially depend on the presence of gravitational forces. Such phenomena include the flow of liquids and, more generally, the formation of "neat" interfaces.

Basically, the behavior observed in ODYSSEY simulations closely mimics that of macroscopic samples in the absence of gravity (such as on any spacecraft).

Physical Behavior If I cool a liquid to below its freezing point, why doesn't it freeze?

ODYSSEY focuses on real simulations of physical phenomena, rather than on cartoon-style animations. While the freezing transition can be simulated, it is very hard to do and requires sample sizes and time scales that lie beyond the scope of ODYSSEY.

Physical Behavior If I melt a crystal of ice, why doesn't its density increase?

For a number of reasons, ODYSSEY performs its simulations with unit cells of constant volume. The user has to manually adjust the volume in order to represent changes in density:

Alternatively, the Build Cell Liquid tab can be used for density adjustments.

Physical Behavior When I dissolve a molecule of hydrogen chloride in liquid water, why doesn't it dissociate?

While ODYSSEY is capable of representing a large variety of physical and chemical processes, the program cannot directly carry out real-time simulations when one or both of the following apply:

The dissociation of strong acids falls into the first one of these categories. If desired, models of the dissociated species—such as (Cl–)aq and (H3O+)aq, (H5O2+)aq, or (H7O3+)aq—can be built with ODYSSEY's Atomic Model Kit.

Physical Behavior If I have a sodium chloride–water interface, why don't the ions gradually dissolve?

While ODYSSEY is capable of representing a large variety of physical and chemical processes, the program cannot directly carry out real-time simulations when one or both of the following apply:

The process of dissolving an ionic solid falls into the second one of these categories. The issue can still be addressed by building "snapshots" of the system in various stages of the dissolution process (such models can be found in ODYSSEY's Molecular Stockroom).

Physical Behavior I built the same system as found in the Molecular Stockroom, but it doesn't behave the same. Why?

When building molecules and bulk phase samples from scratch, ODYSSEY draws on a set of all-purpose rules and parameters (since the structure space of chemistry is huge and the computer obviously doesn't exactly know what you are after). Models in the Molecular Stockroom, on the other hand, are sometimes defined with custom settings that help with improving the general quality of the model.

As a consequence, self-built models will occasionally not "behave as well" as the pre-built models. However, it is rare for a self-built model to behave completely differently.

Importing / Exporting / Annotating Can all molecular models be saved?

Yes, the currently displayed model can always be saved as an .xodydata file (or .odydata file) into locations outside of the ODYSSEY folder (the ODYSSEY folder is Read Only in order to preserve the integrity of the software):

The following restriction applies when saving models:

Importing / Exporting / Annotating In what format should three-dimensional models be saved?

The default file format is ".xodydata" which is XML-based and includes a complete record of the model except for wavefunction-based surfaces (the latter can be read with ODYSSEY, but not be saved).

The alternate .odydata format is needed for two purposes:

Importing / Exporting / Annotating Can I open saved models with "drag and drop"?

Starting with release 2.1, all ODYSSEY files (.xodydata, .odydata, or .odyssey) and also all .spartan files can be opened by dragging the file onto the desktop shortcut created by the installer.

Importing / Exporting / Annotating Can pictures of the molecular models be saved?

Yes, screen shots of molecular models can be saved in several formats:

Tip: For best resolution, hide the text panel (in the View, uncheck Text) prior to saving the screenshot.

Importing / Exporting / Annotating Can I import files from other modeling programs?

ODYSSEY reads .pdb files (generated by most other modeling programs and also the file format of many databases) as well as .spartan files (generated by Wavefunction's program SPARTAN). Use File Open in order to import an external file.

Importing / Exporting / Annotating Is ODYSSEY compatible with Protein Data Bank files?

Yes, ODYSSEY can serve as a high quality viewer for any Protein Data Bank file.

Importing / Exporting / Annotating Can I annotate the text pages?

Yes, all ODYSSEY Experiments and most of the pages in the Molecular Stockroom can be individually annotated:

The annotations for a given Experiment or Stockroom entry are retained by the computer and will be shown whenever you return to the corresponding Notes page later.

Importing / Exporting / Annotating Can I add my own content?

Customization of ODYSSEY content can be carried out in the following ways:

The text portion of ODYSSEY is HTML formatted and can in principle also be edited. However, technical expertise is required as technologies other than HTML are involved. Also, Wavefunction's copyright must not be infringed.

Adding entirely new topics and new pages to ODYSSEY's content portion is not supported. Please contact Wavefunction with suggestions for incorporation of new content into future releases of the program!
