HETATM modelling query -reg
Respected Sir
i am trying to add my model one zinc HETATM, but my efforts are failed , *iam getting *ATOM in my file pdb instead HETATM in the template structure Experimentally solved Residues Region *191-609* , protein Total Length: *419* in that Five residue are Missing Residue
Here i mentioned
Alignment file

# Homology modeling with ligand transfer from the template 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']
# Read in HETATM records from template PDBs env.io.hetatm = True
a = automodel(env, alnfile = 'TvLDH-2DW0A.ali', # alignment filename knowns = '2DW0', # codes of the templates sequence = 'TvLDH') # code of the target a.starting_model= 1 # index of the first model a.ending_model = 5 # index of the last model # (determines how many models to calculate) a.make() # do the actual homology modeling
kindly give provide your valuable suggestion regarding error

Most likely you have an alignment error, and are aligning your '.' residue in the model with an ATOM record (rather than the ZN HETATM) in your template.

There's definitely something wrong here, since your alignment contains 415 residues but you've asked Modeller to read 414 from the PDB file. That can't possibly match.
