[modeller_usage] help--model-segment.py

["" <>]

Hi:
   I use 'model-segment.py' to build the structure of my target protein, the
following is the script:
from modeller import *
from modeller.automodel import *
log.verbose()
class mymodel(automodel):
    def select_atoms(mdl):
        return selection(mdl.residue_range('37:A','63:A'),
mdl.residue_range('74:A','96:A'),
mdl.residue_range('111:A','133:A'),
mdl.residue_range('153:A','173:A'),
mdl.residue_range('203:A','224:A'),
mdl.residue_range('250:A','274:A'),
mdl.residue_range('287:A','308:A'))
env=environ()
env.io.atoms_files_directory='./:../atom_files'
env.edat.nonbonded_sel_atoms=2
a=mymodel(env,
          alnfile='1u19-tm.ali',
	  knowns='1u19',
	  sequence='mrg-tm')
a.starting_model=1
a.ending_model=1
a.make()
after running the scripts, it appears some errors:
Traceback (most recent call last):
  File "selection.py", line 22, in ?
    a.make()

    raise KeyError, ("No such residue: %s" % indx)
KeyError: 'No such residue: 37:A'
The residue numbers in the model are really the same as residue numbers in the
template.
After 'mod9v1 model-segment.py', it produce the 'tm-mrg.ini' and
'tm-mrg.scr'files, if the script is wrong, dose it produce results else?
ps: is there any diffference between the .ini files and .pdb files?
