This is a ccp4 and O question about maps.  I'm in space group P3, and have
low-resolution phases (PHIB, FOM, or H-L coefficients) from SOLVE in the
mtz file.  I can use fft to generate a simple FOBS map:
   F1=FP SIG1=SIGFP PHI=PHIB W=FOM
and either use the default, or specify XYZLIM 0 1 0 1 0 1.

When I use the map in O, there are parts of the map that are "missing."
When I am building, so I have to confine myself to the primary unit cell,
around 0 to 1 (fractional coords) in O?
