[chimerax-users] Selecting residues in two chains

[Elaine Meng]

Hi Phil,
Maybe the problem is that you needed to hide the other stuff first?  Here are some possible commands:

hide target ar
show /B:19-24 /C:1-190 target ar

...or if you only want to show atoms, not the ribbons, omit the  "target ar" from the "show" command; in show/hide commands, target a is atoms (default),  and target r or c is ribbons aka cartoons.

The slash symbol indicates chain ID, and the colon indicates residue numbers or names:

I hope this helps,
Elaine

Each chain is modeled with structured and unstructured regions.  I would like to only show residues 19-24 of Chain B and residues 1-190 of Chain C in the display window.
