Dear PyMOL Users I'm trying to remove water molecules from a crystal structure which are on the crystal surface while preserving the ones within the crystal interior. What I do is: select waters, resn HOH # cmd.select(waters, (waters extend 1), enable=1) get_area waters, load_b=1 remove waters

Hi James, the beyond operator yields true only if the considered atom pair distance is beyond the threshold in ALL states. To remove atoms which are beyond threshold in ANY state, try this: python for i in range(cmd.count_states()): cmd.select('tmp', 'solvent beyond 5 of polymer',

Hi Thomas, I wounder to know what corrections should I add to the below selection in case of multi state object remove solvent beyond 3.5 of polymer e.g I'm working with the MD trajectory saved in PDB format. I've decided to deleate all solvent from all 100 frames simultaneously but the above

Dear List In a crystal structure, there are usually a number of relevant crystal waters, as well as water molecules on the surface. In our approach, we model the protein structure within a dielectric continuum, so surface water molecules are not required (to save computer time). However,
