Dear Francesco, Probably you just need to use "vop cover" as described in these previous posts: <https://www.cgl.ucsf.edu/pipermail/chimera-users/2013-September/009142.html <https://www.cgl.ucsf.edu/pipermail/chimera-users/2013-September/009142.html>> <https://www.cgl.ucsf.edu/pipermail/chimera-users/2020-July/017021.html <https://www.cgl.ucsf.edu/pipermail/chimera-users/2020-July/017021.html>> Details on the "vop cover" command: <https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/vop.html#cover <https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/vop.html#cover>> For future: the recommended address for questions is chimera-users@cgl.ucsf.edu (CC'd on this message) ... since I'm not the expert in everything (or might be sick or away from work), it's helpful if more people see the question!

Dear Elaine, I am using Chimera to get a picture of a small molecule (cif file) in an electron density map (xplor file). My issue deals with the position of some atoms of the molecule in an adjacent unit cell (see attached image) which prevents me to see some atoms within the map. I thought to simply expand the map beyond the cell boundaries and eventually crop the map, but it didn’t work. I have checked different tutorials and the chimera mailing list for troubleshooting but I haven’t found a solution to this problem. Is there something you can think of? Thank you. Regards, Francesco Papi
