Hi, worth to try moleman -> %moleman Choose READ_pdb_file -> "your_pdbfile.pdb" Choose AUTO_chain_segid Choose WRITE_pdb_file -> "out.pdb"
Or the tedious NEDIT way Open your pdb.file in nedit, mark ONLY the chain ID column -> put your cursor before the first "X", press [Shift]&[Ctrl], go the the last "X" in your chain. Then perform a "replace/Find" by selecting only the "Selection" option ... done. Repeat for each chain.
