Hi there!

I have two questions regarding using Chimera.

How do you break a molecule to different models using the command line?

I have a protein composed of 4 chains. It loads as one piece and designated model 0

I then select a single chain and I want to designate it as a new model. How do I do that using the command line (so I can write a script)?

Also, when I select the chain and use the write command in this manner “write selected su1.pdb”  the save dialog box pops up (even though I designated a filename)

When I try “write selected 0 su1.pdb” nothing happens.

My other question is:

How can you force chimera to assign secondary type display to residues without editing the PDB file first?

Say I want to show 30 residues that are not detected by ksdssp as beta sheets. Still, I want to represent them as beta sheets. Do I need to edit the pdb file?

Best regards
