[Chimera-users] Show position in volume

[Thomas Goddard]

Hi Magnus,

   After placing a marker use the command (Favorites / Command Line)

	getcrd sel

to show the coordinates in the status line and reply log (Favorites / 
Reply Log).  The "sel" part of the command means to show the coordinates 
of selected objects.  After you place a marker it is selected (green 
outline).  If it becomes unselected use ctrl-click on it to select it.

   The coordinates are the volume x,y,z coordinate system using the 
voxel size and origin specified in the volume dialog coordinates panel. 
  (Actually the coordinates are those of the marker model which will 
match the volume as long as you don't move one with the other frozen.) 
If you want array index coordinates you should set the voxel size to 1 
and origin to 0,0,0.

   There is no way to get coordinates of a point without placing a 
marker.  The trouble is how would you specify the depth using just the 
mouse?

	Tom
