Re: [modeller_usage] loop refinement with disulfide patch

["M. Seigneuret" <seigneuret@cochin.inserm.fr>]

Thanks.
Unfortunately, the script stopped after a few seconds. Nothing special 
in the log (except that it was short), but this at the command prompt:
'import site' failed; use -v for traceback
Traceback (most recent call last):
  File "model-loop.py, line 21, in ?
   m.make()

Strange. It seems to complain that special_patches has 2 arguments 
instead of 1, while it has actually 1 in your script and 2 in the manual 
examples.
Thanks again for your help.
