This is what I don't know whether the license that current versions of RasMol use would cause problems, but older versions of RasMol (up through about 2.6) are public domain, and it looks like they probably have about the same DSSP code as the current version. So there's probably no licensing problem as long as we start with the old version. I have done some work with interfacing RasMol to Python, so it might be fairly easy for me to interface it with PyMOL. I will look at it in the next few days to see how hard it would be. n...@mail.csb.yale.edu (Nathaniel Echols) writes: >The other thing I'd find useful is some molecular mechanics tools, >particularly energy minimization.

There shouldn't be any licensing problems, and you could probably get some help from Konrad Hinsen (the main author of MMTK), but I suspect it would be a good deal of work to do it cleanly. It might be fairly easy to kludge something up that involved communicating with MMTK mainly via pdb files. -- ------------------------------------------------------------------------------ Peter McCluskey | Free Jon Johansen! http://www.rahul.net/pcm |
