Hi Leila,
What feels like two centuries ago, we had written a program that would
read a ccp4 map and produce a postscript plot containing both contours and
a dithered grayscale representation of the map. This is useful for complex
projections like the one shown in [1]. The program (mcps) is
Dear Leila,
The CCP4 program FFT, which generates 3D maps from reflection data
can also produce projections. Use the keyword PROJECTION. It will only
give projections down an axis but if the X-ray SG is trigonal then you
will be OK. Another CCP4 prog MAPSLICER can be used to view the map.
Hi Leila,
it was 10 years ago when I looked at the maps this way, and at that time I
used the program called CAN to do this (see below). It worked really well.
If you are lucky it might still be available by request from the authors.
Pavel.
