[Chimera-users] Comparison of cryo-em maps

Depends what you mean by “compare.”
Some thoughts are:
(A) subtract one map from the other to see the differences: command “vop subtract”
(B) show the same isosurface level for both, Measure Volume and Area (under Tools… Volume Data) or the corresponding commands “measure volume” “measure area”
(C) morph between their isosurfaces with Morph Map tool or command “vop morph"
This tutorial has an example of morphing between two EM maps (about halfway down the page):
I hope this helps,
