[Chimera-users] Crystallographic Map Expansion

I am trying to open a map generated by microED. I generated a SigmaA map in
coot based on an fcf file generated by SHELXL (see attached). I can open it
in Chimera and things look reasonable. I am wondering if it is possible to
expand the density map beyond the boundaries of the available box using the
crystallographic symmetry? Additionally, I am a bit confused by the size of
the box. I would have expected it to have the dimensions of the unit cell
or the asymmetric unit, but it does not appear to be either of those. The
map does appear to be scaled properly.

Any help would be greatly appreciated.
