Thanks for your replay. I am not sure how to rename an atom selection in a
trajectory. Would you please give an example?
We were using BDDM topology from toppar_all36_lipid_detergent.str to
generate psf of dodecyl-beta-D-maltoside detergent. The atom names start
with numbers, like 1C1, 2O1,... then psfgen was complaining about it and we
mistakenly replaced numbers with 'A' and 'B' letters.
