[Chimera-users] Combine maps

[Tom Goddard]

Hi Jian,

  You can add your two maps with the volume operation command

	vop add #1,2

This will create a new map with grid points that align with map #1, with map #2 interpolated (trilinear interpolation) at those grid points.  The bounds of the new map will extend beyond the bounds of #1 if that is needed to cover map #2.  Here is documentation

	http://www.cgl.ucsf.edu/chimera/current/docs/UsersGuide/midas/vop.html#add

If density in your two maps partially overlap each other then adding them together will create extra high density in the overlap region which is probably not what you want.  How to blend them together in the overlap region is a difficult problem that Chimera does not have any capability to handle.

	Tom
