[PyMOL] Changing Chain ID

[<pat...@lo...>]

Hi – I’m a high school student learning to use Pymol for my science fair research, and I’ve been using Pymol for about 6 months. I have been working on attempting to bind a protein to actin for over a month now – but whenever I fuse the linker to the antifreeze protein, it glitches. As well, when I save my actin chain with all the linkers fused as a PDB file and reopen it, only one of the linkers is visible. I’m hoping you might be able to help me figure out what I’m doing wrong.

Schrodenger support provided a recommendation. Part of it is to rename the protein chain to something else (e.g., chain F) so that it wouldn't interfere with chain A from the F-Actin chain. I’ve been unable to figure out how to change the name/ID of my chains. I have tried changing to “3 Button Viewing”, selecting “Chains”, clicking on the chain of interest, clicking on the selection “A” action button and selecting “rename selection”, as well as using the "set_name" command, but neither are working.

Can anyone help me figure out what I’m doing wrong?

Thanks so much!
