Dear Chimera Team/Users, I wanted to write a python script within chimera that aims to essentially print out a contact map of a selected chunk of residues on an open structure. However, before doing so, I wondered if there is any programmatic way to generate the rotamer library at every position (i.e when you open up the rotamer tool, you get an option of 5-6 conformations you can pick for a residue), I wanted to generate that for every residue in the protein programmatically (and save every rotamer possibility) (as an altlocation?) in the crystal structure. Only after that do I want to calculate the contact map, in essence, I am trying to be as expansive as possible for each residue's "possible" contacts with any other, taking into account the full rotamer ensemble. Any tips on how to manage this programmatically? -- Dr. Ahir Pushpanath* PhD.* Senior Biologist, Johnson Matthey.
