First let me say that PyMol is the most useful and powerful open-source software I have come across.
I am running the 0.78 version, installed from RPM onto a RedHat Linux 7.3 system with an nVidia Vanta graphics card. I have a few comments: 1. There appears to be a bug in the isomesh routine (see comment submitted to the Sourceforge bugtracker). I haven't tried the latest CVS version though. 2. Some suggestions for improvements to PyMol: a) Automatic creation of sub-objects for protein structures After loading in a structure (e.g. a PDB protein file), would it be possible to have the option of automatically breaking it into an object for each chain, and one for each ligand present in the structure, so that the user could quickly click on/off the required components? (This could be extended into a heirarchical tree-structure, in which chains, residues, atoms would all be available via the object list on the control panel) b) Graphical summary of density distribution for map data A feature which popped-up a histogram of density values, which could alter an isomesh contour value by clicking on it, would be extremely useful. Also, is there a way to have a '.pymolrc' file containing commands which are run whenever PyMol starts? Please keep up the great work! Gareth
