As I understand it, Coot may automatically use symmetry to display the map so that it covers the atomic structure.
In Chimera, the map isn't automatically extended or translated to cover the atoms, but you can do so using the "vop cover" command:

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.
