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
