STR3DI TEMPLATES for MOLECULAR MODELING and MOLECULAR GRAPHICS.
Using suitable template structures, you can assemble the most complex molecules easily and efficiently using STR3DI32. Often the problem is finding a suitable template structure. We will try to supply you with these, on request, and will often post them on this page if enough users ask for these structures.
Click here to get The Basic Set of Template Structures that are packaged with the STR3DI molecular Modelers. We also provide you with a set of amino-acid structures (in this zipped file), for use as templates.
The structure data files listed below were actually placed here to demonstrate the ability of STR3DI32 to perform as a "helper" application, or “plug-in”, with the Microsoft Internet Explorer web browsers.
The molecular models embedded in these structure data files will also start you out on your molecular modeling experience at your web/home/classroom/lab workplace.
Normally, provided that you have associated the SXS, XCC and XXS file extensions with STR3DI32, if you left-click on one of the structure URLs below the browser should download the file into the “Temporary Internet Files” folder, and then execute STR3DI32 and use it to open the structure file you clicked on.
As much as we really like using the Mozilla FireFox browser, it does not “read” file associations from your computer’s operating system, registry, (maybe Microsoft’s copyrights prohibits this), and FireFox has not yet been adapted to enable users to easily add “custom” plug-ins or mime types. So if you are using FireFox, when you left-click on a datafile it will simply be opened to show the contents, but you can save these files to your disk drive and then use them off-line.
If you have associated the STR3DI extensions, and you still get an error when you left-click on any URL below, then you have a small problem of a missing key in your system’s Registry. When you had associated the file extensions .sxs and .xxs with STR3DI32, the computer should have created these Registry Keys. It might be that the system did not do so, or later erased them. We can supply you with the Registry Keys that will enable your computer to become fully compatible with STR3DI32’s files. The problem of the missing Registry keys seems to be most prevalent in systems running Windows XP.
You can also right-click on the URL and use the option to save the file to your hard disk drive. From there you can continue to examine the structure using STR3DI32.
If you wish to use STR3DI32 in online molecular modeling exercises, then we have to recommend that you use the Microsoft Internet Explorer web browser.
