I'm trying to do a loop refinement calculation with the dopehr_loopmodel class, modeller 9v4.
Here's the python script I'm using:
from modeller import *
from modeller.automodel import *
log.verbose()    # request verbose output
env = environ()
# directories for input atom files
env.io.atom_files_directory = ['./', 'PDB/']
a = dopehr_loopmodel(env,
              alnfile='TTN.ali',
              knowns='2g8gOligo',
              sequence='1s58',
              assess_methods=(assess.DOPE, assess.GA341))
a.starting_model = 1
a.ending_model   = 1
a.md_level       = None # No refinement of model
a.loop.starting_model = 1
a.loop.ending_model   = 1
a.loop.md_level       = refine.fast
a.make()

After a few hours of running, it stop. Here's the last part of the log:
...

              The objective function can thus not be calculated.

The model part went OK, but when it tried to do the loop refinement it went crazy (the coordinates in1s58.BL00010001.pdb are all messed up).

I'm also testing the other two classes (loopmodel and dope_loopmodel) and they've been running for a long while now, so I don't know if they'll work or not. I'd just like to
know if I'm doing something wrong or I just ran into some kind of glitch or bug in the dopehr algorithm.

Thanks!
