Hi Sara, I can't think of a fancy way. Probably you need to just select the unwanted atoms and then use Actions... Atoms/Bonds.... delete, or command: delete sel Usually to avoid this kind of thing from zoning you would use a residue-based cutoff on the zone instead of atoms. Then only whole residues would result. I hope this helps, Elaine ----- Elaine C.

Hi all, Is there any way to select (or directly remove) atoms without substituents?
The situation is that I have to cut a region of a system. So, after selecting by zone without including the entire residues, I save the selection and I get some single atoms that I would like to get rid of. For example, in the attached file I got H atoms, C atoms, and also C2 chains that do not have any sense even if I complete their valences by adding H. Notice that in such a way they will become H2, CH4 and CH3CH3, respectively, which are very strange molecules for my system that actually contains phospholipids, ibuprofen, and water. I would like to know if there is any automatic tool to do it, for example defining an attribute or using the command line.
Any help is appreciated. Regards, Sara
