 >I recently ran into a problem creating masks with mapman.   
Contouring at
1.5 (qmap) appeared suitable for mask generation; however using 1.5  
as the
cutoff in mapman results in an null mask.

can't help with the above but since gerard is away, i'm not sure if  
he'll be able to reply, so i\d do it this way:

if you already have operators, i'd make a spherical mask centred on  
the middle of your molecule with ncs_mask_sph in o, then average,  
don't expand to the cell, then skeletonize, edit skeleton to your  
heart's content, make a better mask with ncs_mask_sph & a few  
NCS_mask_lay and use for averaging in o.

if this is mol. replacement, you make a map from one molecule  
immediately with ncs_mask_sph etc

without operators, try NCS_operator
