Hi Osama, I think Elaine's procedure for finding coordinates is the way to go. But it is pretty tedious. It would be nice if you could just show a plane of data and have it report the position on the plane as you move the mouse to any desired position. Also would be nice if placing a marker in the way Elaine said would report the coordinates without having to use the separate getcrd command. I'll submit feature requests for these improvements.

Hi Osama, You could try using the "Volume Tracer" tool (under Tools... Volume Data) to place marker spheres at the location of interest. <http://plato.cgl.ucsf.edu/chimera/docs/ContributedSoftware/volumepathtracer/framevolpath.html>
Use the Mouse menu on that tool to control how the markers are placed.
Then if you select a marker sphere with Ctrl-click and use command "getcrd sel" it will report the coordinates. The coordinates should be in the same system as the volume, as long as you don't move the markers separately from the volume. <http://plato.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/getcrd.html>
I hope this helps, Elaine ---------- Elaine C. Meng, Ph.D. UCSF Computer Graphics Lab (Chimera team) and Babbitt Lab Department of Pharmaceutical Chemistry University of California, San Francisco
