I need to change the chain ids for 10000 pdb structures generated by the relax protocol. I have 2 chains A and B in each protein (antibody) and I want to change them yo H and L (as antibody_H3 seems to request that the heavy chain of the antibody should be name d'H'). I saw in older posts that there should be an utility:
changeChain.pl - change the chain ID of a specified chain from a pdb file.
but I cannot find it the Rosetta source.
