There is kind of a "cheaty" way to do it if you are using the 1.2255 snapshot by saving a session file and editing it. You need to use an editor that can handle long lines, like TextEdit.app on a Mac or WordPad on Windows. Search for the string 'chain' (including the quotes). You'll see some text that looks something like: 'chain': (29, 'A', {}) change the A to B so it looks like: 'chain': (29, 'B', {}) save the edited session and open it in Chimera and the chain ID will have changed. --Eric On Aug 28, 2006, at 1:36 PM, Elaine Meng wrote:
Hi Yunierkis, Sorry, there is no way to change the chain ID in Chimera. You would need to text-edit A to B in the PDB file before opening it. (Or, if you're fetching the structure from the PDB, write it out in PDB format, edit the file, and read it back in.)
Depending on what you are trying to do, there may be some way of doing it without changing chain ID. Best, Elaine

Hi all,
I need to change the chain ID for a protein, that is, change the chain A to chain B. Can I do that with chimera?
Thanks in advance Yunierkis
