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.

I would really like to be able to take my electron density map (from X-ray) and view it as a 2D projection of 3D space (essentially a contour map). The attached is an example of the type of electron density map I'm trying to mimic. Does anyone have any suggestions on what software I could use to do this? > > Image Source: J Mol. Biol.
