Hi Ahmad, To my knowledge the map subtraction is precise. But if you think there is a problem, you will need to give a precise and detailed description of exactly what you did, including the data files and all the steps needed to show the problem, and why you believe there is a problem (and possibly use menu: Help... Report a Bug, instead of sending e-mail here). If we can't reproduce a problem, we can't fix it! It may be that you need to create the molmaps with smaller grid spacing to give a more precise result. molmap details and options: <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/molmap.html> vop subtract details and options: <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/vop.html#subtract> Elaine ----- Elaine C.

I'm trying to subtract two overlapping molmaps: map1-map2, but the subtraction ends up removing too much of map1 where map2 doesn't overlap with map1!
how can I get precise subtraction?
