Dear Neha, It is right as per my opinion. if the end residue is missing no issue. join the ligand pdb and receptor pdb and use pdb2gmx directly . no need to do as per total process of Justin tutorial. As justin tutorial is for the non-amino acid residues. use properly the pdb2gmx command a

Hello Rama david Thank you very much for your reply. The residue is missing from the middle as well as from the end. Hence I have modeled it with the help of homology modeling. Then I align both the protein (PDB downloaded as well as homology modelled) and get a RMSD fluctuation of 0.45 with the

Dear Neha, the question depend on which residue is missing?? Is the residue is from middle or from end that is important. If end residue is missing then no issue. but middle residue is problematic. you can model the protein and then align it with pymol align command or any other visualizing

Hello All I am performing Molecular dynamics simulation of protein-ligand complex using charmm36 force field in popc lipid. I downloaded the protein ligand complex pdb file. And as mentioned in Justin A. Lemkul protein-ligand complex tutorial I have seperate ligand and protein from pdb file. My
