Not sure if this helps, but MAPMAN contains options to make 1D and 2D projections - see http://xray.bmc.uu.se/usf/mapman_man.html#S45 Many moons ago, I also wrote a script to generate general projections (e.g., onto the plane of an aromatic ring) using various USF programs - you may want to try and resuscitate that (I would be very surprised if it worked out of the box) - ftp://xray.bmc.uu.se/pub/gerard/omac/plane_extract.csh --Gerard On Sat, 27 Nov 2010, Jeffrey D Brodin wrote: > Hi all, > > I'm currently working on a project where we are attempting to compare a single crystal X-ray structure with 2D crystals we've imaged with TEM.

We are pretty sure, based on electron diffraction, that the 2D crystals contain a screw axis, as did the X-ray structure. Also, after generating the images, is there another program that will calculate structure factors and a diffraction pattern?
