Hi,

I try to do homology modeling by the automodel class. I get this error:

File "/usr/lib/modeller9.12/modlib/modeller/modeller/restraints.py", line 170, in make_distance
    raise TypeError("restraint_group should be a physical_type object")

# Homology modeling by the automodel class
from modeller import *              # Load standard Modeller classes
from modeller.automodel import *    # Load the automodel class

log.verbose()    # request verbose output
env = environ()  # create a new MODELLER environment to build this model in

# directories for input atom files
env.io.atom_files_directory = ['.', '../atom_files']

a = automodel(env,
              alnfile  = '1FLZ-WT-MU.ali',    # alignment filename
              knowns   = '1FLZ',              # codes of the templates
              sequence = '1FLZ-H15Y-H206R')   # code of the target
a.starting_model= 1                 # index of the first model
a.ending_model  = 1                 # index of the last model
                                    # (determines how many models to calculate)
a.make()                            # do the actual homology modeling
