[Chimera-users] [chimera-dev] fit map in map -- also fit a/pix at the same time ?

Chimera cannot optimize the volume grid spacing when fitting a
molecule model. I agree that would be useful. I'll add it to our
requested features list.
You can do this scale optimization by hand using the volume dialog
Coordinates panel to change the voxel size (press the return key after
you change the number), then press the Fit button on the Fit in Map
dialog. With small scale changes the fit should converge each time and
you can quickly try several different scales. The newer Chimera
releases (Jan 31, 2008, 1.2492) available on the daily builds page can
make a simulated map for your molecule at the desired resolution and
report correlation coefficients which is probably better than average
map values for this scale optimization.
