It depends on how you want to visualize the data. If dots/points or other
discrete representations are okay then you can use a XYZ or a modified
structure file. If you want the benefit of a field (volume, gradient,
isosurface) then I suggest the map.
If you already have the data in a well-formatted brick, check out the
asCCP4 function in http://www.pymolwiki.org/index.php/Tiff2ccp4. That
writes the CCP4 header and data (of a TIFF file, but you can modify that
for your needs).
If you want, send me a copy of your data. Or, I also have a very poorly
written script that will convert raw volumes of data to CCP4 maps, similar
to the aforementioned script. Email me personally and I can send you a copy
if you prefer (but it's really ugly code).
Cheers,
-- Jason
