Hi Tom, I was talking about this: "Resample map commands newmap 100 100 100 2.4 2.4 2.4 -120 -120 -120 This command creates a new map containing zero values of size 100^3 grid points with grid plane spacing equal to 2.4 and origin (i.e. physical xyz position of grid value at index 0,0,0) equal to (-120,-120,-120). An outline box is shown for the new map." Here I could create a new map at a specified position with specified size but the Atom Box feature will be fine and the "getcrd sel" command also. Thank you, Elaine and Giovanni! At last, a feature request: it would be convenient if I could open IMAGIC files directly in Chimera.
