Hi Francesca, I can't say for certain without having your exact PDB file to test, but some things to try would be delete solvent & :546-893 - or - delete :546-893.water How these water residues are written (and thus how to specify them) depends on the program that made the file. I hope this helps, Elaine ----- Elaine C. Meng, Ph.D. UCSF Chimera(X) team Department of Pharmaceutical Chemistry University of California, San Francisco

Hi, I have a problem using Chimera: I need to delete specific water molecules with a specific residue number, but this number is in common with residues that are useful (such as ligands or co-factors). For example, I type "del :546-893" in the command line in order to delete these water molecules, but I delete also the ligand and FAD and I don't want to. I've read the guide about atom specification, but still I don't know how to do it. Hope someone can help me, thank you. Francesca
