RasTop 2.2

A handy visualisation program
To fully understand chemistry you need to visualize it. At the rate of which technology advanced, it is possible to do so from the comfort of your desktop chair. Doing so is only available through special applications, just like RasTop.

In depth molecule visualization

With the help of this little utility you are able to better understand what is going on at an atomic level. RasTop allows you to view any proteins, nucleic acids, and small molecules created with Rasmol.

Use your mouse to navigate around, or by the press of a button you can make it automatically spin while you sit back and analyze. Different view modes are available, ranging from wireframe, to ball and stick, according to your liking.

An abundance of options

RasTop is anything but missing view options, and it won't leave you clueless for a second. The basic rotation options ensure that everything can be in sight, while tabs can be opened for more in depth analysis, such as number of atoms, groups, and much more. Specific components can be hidden, or shown, depending on the case, to ensure an even better understanding.

Multiple molecules can be viewed at the same time, as well as a “Stereo” option, that will split the workspace into two, allowing for different angles to be visible simultaneously.

In conclusion

To sum things up, RasTop offers a highly complex view on what's going on at a molecular level. This makes it a suitable learning application, that can come in handy to those students that simply cannot comprehend chemistry. Moreover, the ability to save under one of the common image file types, gives you the ability to share info with people that lack this handy utility.

What's New in version 2.1
  • Numerous bugs have been corrected, thanks for all of you who reported them.
  • A command window similar to the one in the original RasMol program has been added.
  • This feature was requested by numerous teachers and was initially developed by Christian Duque. RasTop is now localizable to multiple languages, see RasTop help. A 'scripting' toolbar has been added to improve the handling of scripts. Scripts located in the "rastop/scripts" folder are directly accessible on the new toolbar. Images can be saved as bmp files in 32-bit format.
