[Chimera-users] [chimera-dev] Dividing a model into seperate models - one for each chain

Hi Tom,

Thank you very much for your response.

My exact problem is that I'm trying to find a way to automatically save all
the models (and submodels) that are opened in Chimera at a time. It's easy
when models are numbered #0, #1, #2 etc - then, I use:

while howmany>=0:
     command="write "+str(howmany)+" "+o_path+"/"+str(howmany)+".pdb"

Unfortunately, when I split, let's say, #0 that contains 3 chains, and then
use the above code, I get an error:

MidasError: 3 model ids match "0"

So maybe there's a different way to do it? I'd like to save #0.1, #0.2 and
#0.3 to seperate files. I know it's possible from Chimera's interface, but
I have no idea how to do it when my script doesn't have any info about the
number of submodels etc.

Thank you for your time once again,
