modeling cis-proline



Hello-

I just wanted to make sure the below script looks correct for telling
modeller to make a certain proline (in my case, residue 10) in the
cis-conformation.

I've seen a few ways of either doing it directly (as below) or making a
constraint file after the fact (or before?).

I tried to use the below script, and I'm not sure if it's doing it
correctly (so I wanted to check to see if the script was OK).

Thanks for your input,
Doug Kojetin
