[chimerax-users] create chain as a new model from exiting PDB model

[Elaine Meng]

Hi Tim,
You could either 
(1) use command "split" to split the existing model into separate chain models (or /A vs. everything else)  For example, if existing model is #1 with chains A-D, command:

split #1

... will split it into model #1.1 with chain A, model #1.2 with chain B, etc.  Close the extra models that you don't want.  If you still need the original model you would just open another copy.  Help for split:

(2) simply delete everything that is not chain A, command:

delete ~/A

If you also still need the original model you would just open another copy.  Help for delete:

I hope this helps,
