Dear all,
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)
2. .ali file

Bcz, total residue count is 1290 and chains are A, B, C (chains are specified using the chain breaks). Is it correct please guide me on this. Will that read the hetatms too? Because when I run this and generate model. It didn't include the het atoms.
Please help me on this. Sorry for the inconvenience.
Thanking you, Nirali

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.
