Editing RUCAP UM-5 (section)

== Getting UM-5 data of the users position into socket by your script rucap.py ==

This device has got only OS Windows support on current time.

First, you need runing PyMol with [https://code.google.com/p/immersive-viz/source/browse/trunk/MolViz.py MolViz.py]. And optional with [https://code.google.com/p/immersive-viz/source/browse/trunk/MolVizGeneratedGui.py MolVizGui.py], that make fine settings of interface RUCAP (That is  [https://code.google.com/p/immersive-viz/wiki/UserManual UserManual] for GUI). Any model is good, but for example, [https://code.google.com/p/immersive-viz/source/browse/trunk/1jnx.pdb 1jnx.pdb] you will take from the same [https://code.google.com/p/immersive-viz/source/browse/trunk/ repo].

     ./pymol -l MolViz.py 1jnx.pdb | python MolVizGui.py

MolViz.py runing the [https://code.google.com/p/immersive-viz/source/browse/trunk/SocketServer.py SocketServer.py]. 

For convert data to MolViz format you need run next socket script client '''rucap.py''':
