[Chimera-users] Select multiple chains

[Elaine Meng]

Hi Vincent,
Chain ID generally is one character, and at least in that “normal” situation you can just give a range:

select :.A-D

…or specify individually all mashed together:

select :.A:.B:.C:.D

You can try those.  I don’t have 2-character chain IDs example handy, so it’s possible the behavior is weird in that case.

In ChimeraX there is a convenient way to select all the polymers with the same sequence, but we don’t have anything like that in Chimera. In ChimeraX, this command would select all the chains with exactly the same sequence as chain A:

select polymer /A

ChimeraX has much better performance on large structures, but not all the same features as Chimera, although the list is longer every day...

I hope this helps,
