The ligand is chain X at 2q3z = /.P.LPF./
The models are created but without chain B/X or any ligand/polypeptide.
The script:
from modeller import *
from modeller.automodel import * # Load the automodel class
log.verbose()
env = environ()
#Considering heteroatoms and waters molecules
env.io.hetatm = env.io.water = True
# Directories with input atom files:
#env.io.atom_files_directory = './:../atom_files'
env.io.atom_files_directory = ['./', '../atom_files']
a = MyModel(env,
alnfile = 'aln-all.ali' , # alignment filename
knowns =('2q3z', #sequences
'3s3j_L'
), # codes of the templates
sequence = 'P21980', # code of the target
assess_methods=(assess.DOPE, assess.normalized_dope, assess.GA341) #assess model with DOPE
)
a.starting_model= 1 # index of the first model
