[chimerax-users] VOP cover command?

Hi chimeraX forum,

I am trying to get an electron density map (.mrc) to overlap with atomic
structure (.cif) file of a small organic molecule. When I open my electron
density map in ChimeraX, only one rectangle ( i am assuming one lattice
piece) appears, which does not encapsulate the entire small molecule.

I am thinking to use the "vop cover" command to get the density to expand
to multiple lattices, but I am not sure what numbers to enter.  When I try
"vop cover atomBox #2" (#2 is the ID of the .cif structure), I get a
"Missing or invalid 'volumes' argument: invalid density map specifier"
response.

Thanks in advance for any help!!

Megan
