I am performing a local docking using Rosie server for a complex obtained from patchdock. The residue names are checked as in Rosetta nomenclature. But strangely the resulting pdb shows a missing residue, that is the first residue of both the protomers are missing. How is it possible or how to overcome it?
Rosetta rejects protein residues missing one of the mainchain heavy atoms – N, CA, C. Missing residues at chain ends are often due to partly-resolved residues. Are the backbone atoms present in the input, at non-zero occupancy?
