[Chimera-users] Coordinates of atoms and volumes

The Chimera getcrd command will report atom coordinates.  In Python code you can get the coordinates for atom a with a.coord or a.xformCoord if you want to include the viewing direction.

To specify a point in a density map you usually put a marker on it with the Volume Tracer.  A marker is actually and atom so getcrd works for that.
