[Chimera-users] crop a map via commandline

Hi Edoardo,
The “region” option of the “volume” command is the same as setting region min and max in the Region bounds section of the GUI.

For example, if I have a map #3, then command:

vol #3 region 10,10,10,20,20,20

is the same as GUI:

Region min max step  x[10 20 1 ] y [10 20 1 ] z [10 20 1 ]

That adjusts the display.  If you want to save this region to a file, you could instead use the “save” option,  for example, a command something like:

vol #3 save /Users/meng/Desktop/test.mrc saveRegion 10,10,10,20,20,20


I hope this helps,
