[ccp4bb] cns .map in coot

[Julian Nomme]

Hi all,

I can easily convert my composite omit map from cns to ccp4 format and 
open it into coot.
However, how can I make coot use this map to fit density to my structure ?
I can only use this map for visual support and for example, coot doesn't 
assign any density on the bar graph generated by using the "Density fit 
analysis" option to check the geometry.
Does anyone have any idea how to fix this problem?
Thanks,

Julian
