[Chimera-users] Volumes comparison

[Elaine Meng]

Hi Nail,
There isn’t much else to say.   your maps are open as #1 and #2, command:

measure correlation #1 #2

… and then look in the Reply Log (menu: Favorites… Reply Log).  Or to use a dialog, choose menu: Tools… Volume Data… Fit in Map, choose the two maps from the two pulldown menus in that dialog, and then click Update.

The order is important (#1 #2 vs. #2 #1) and the contour level of the first map is important because by default the calculation will only use the grid points in the first map with values above its display contour level.  See the manual pages in the links I sent previously for options such as using all values even if they are outside the contour surface.

I hope this helps,
Elaine
