[Chimera-users] box size limit

[Franken, L.E.]

Dear chimera users,
I am running into troubles displaying a map of a 650x650x650 volume and I
was wondering if there is a box size limit to chimera or what else could be
the problem. The way it displays the 3D .mrc file is as a single slice
rather than a volume. It will also go straight to solid display rather than
surface, did anyone encounter such a problem before? I can open the map in
coot and relion (slices), so I do not think that the map is corrupt. Thank
you for your time.

Best wishes,
Linda
