Dear CCP4BB members, We are using a script written in python to generate symmetry mates for a given pdb file using PYMOL. After generating symmetry mates we want to combine all the symmetry molecules in a single PDB file with all the chains having unique chain IDs. Since all the symmetry mates have same chain ID's I was wondering if some one knows a script that can give unique chain ID for each symmetry mate. We are interested in script because that dataset that we are handling is large. I thank you all in advance for your help. Best,
Krishan
