I have to model missing residues of the protein.
PDB ID: 2hxh
I also want to include het atoms (Ligands) in the resultant model.
I did the required changes:
1. *env.io.hetatm = True *
(Changed this in the model generation script)
This is fine, but only tells Modeller to read HETATM residues from your
template(s).
1. Your alignment file should contain two sequences - one matching the
input PDB, and the second the sequence you want to model (i.e. in this
case, with the missing residues added).
2. If you want to model ligands, you need to add the appropriate number
of '.' residues to the end of both sequences and update the residue
range in the alignment header accordingly. See
https://salilab.org/modeller/9.22/manual/node18.html for an example.
