Hi Aleena, If you have some structures open with blank IDs that you want to change to 'A', I believe the Python code is: from ChangeChainIDs import changeChains from chimera import openModels, Molecule changeChains(openModels.list(modelTypes=[Molecule]), [(' ', 'A')]) --Eric Eric Pettersen UCSF Computer Graphics Lab

Hi Elaine,
Thanks a lot for your reply. The problem is that I have got hundreds of such pdbs with no id chains after random scanning mutagenesis. I wish I could solve it using a python script.
Regards Aleena.

Structure Editing... Change Chain IDs. That dialog will list the chain with no ID separately (something like "principal chain") and you can click to choose it in that interface, then enter a new ID.

Hi, I need help with chimera. In my pdb I have a chain with no id and I want to assign it a new id. I tried using 'changechain' command but I am getting error messages because I don't have any specific from-chain id. I don't know what exactly to give as from-chain id or is there any other command that could help me? Thanks, Aleena.
