Hi Roberto, If using that symmetry without the distance filter would give you "extra" copies, maybe it can be done in two steps by first using the symmetry, and then deleting copies that are farther away. E.g. in ChimeraX something like sym #1 i,222r copies true delete #2 & #1 #>3 The first command uses the symmetry information to make many copies of #1 as #2.1, #2.2, .... and the second one deletes all the #2 submodels that don't have atoms within 3 angstroms of #1. ChimeraX sym: <http://rbvi.ucsf.edu/chimerax/docs/user/commands/sym.html> Specifying distance zones: <http://rbvi.ucsf.edu/chimerax/docs/user/commands/atomspec.html#zones> I hope this helps, Elaine ----- Elaine C.

Dear all,
In chimera I used to use the command
sym #0 group i,222r contact 3
to surround an asymmetric unit cell by its neighbors.
I see that, in chimerax, "sym" no longer has the option "contact" (or the alternative option "range"). Is there any way to get results similar to the ones obtained using chiera command
sym #0 group i,222r contact 3
with chimerax
