[modeller_usage] Including ligand from template



Dear Modeller users!

I've followed 1st modeller tutorial making alignment of my target against 1 template (with the inclusion of hetatm from the template). As the result I've obtained the below alignment


>P1;2rh1A
structureX:2rh1.pdb:  29 :A:+283 :A:::-1.00:-1.00

where Od_r is the modeled protein and 2rh1 is the template consisted of ligand ('.' in aliugn file)

now I'm running script for making models (where ligand should be included from the template and obtain error about atom mismatches

from modeller import *
from modeller.automodel import *


# Read in HETATM records from template PDBs
env.io.hetatm = True
env.io.hydrogen= True
# directories for input atom files
env.io.atom_files_directory = ['.', './results']

env = environ()
a = automodel(env, alnfile='result.ali',
              knowns='2rh1A', sequence='od_r',
              assess_methods=(assess.DOPE,
                              assess.GA341))
a.starting_model = 1
a.ending_model = 10
a.make()

    return f(self.modpt, io.modpt, self.env.libs.modpt, eqvdst)
_modeller.ModellerError: read_te_290E> Number of residues in the alignment and  pdb files are different:      283      282 For alignment entry:        1  2rh1A

how it could be fixed and obtain models with the ligands in the positions identical to the templates ?
