Dear Eduardo, It isn’t exactly the same for atomic structures, but consider these approaches: (1) You can specify exactly which atoms, residues, etc. to display using selections and the Actions menu, or directly using commands. If there is some central area of interest, the atom specification can include a zone operator. For example, to show only residues within 4.5 Angstroms of residue HEM in chain A of 4hhb: open 4hhb ~displayhttp://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/frameatom_spec.html display :hem.a z<4.5 ~ribbon ribbon :hem.a z<4.5 See atom specifications, zones: <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/frameatom_spec.html> (2) clipping. You can adjust front-back clipping in the Side View or with commands, and per-model clipping (affects individual models, can be at any angle) with Per-Model Clipping or with commands. See this page and links within: <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/clipping.html> I hope this helps, Elaine ----- Elaine C.

Dear Chimera users, I find very handy the function “Region bounds” to cut the EM maps in order to better visualise some part of the volume. I was wondering if there is an equivalent for PDBs. Many thanks in advance, Edoardo
