[ccp4bb] how to superpose density maps?

[Matt Warkentin]

Hi all

I have a seemingly simple task that I can't seem to figure out how to
do:  I have a bunch of structures with same space/cell that I want to
compare in coot.  It is easy to superpose the models, but I would also
like to superpose the maps.  Is there a simple way to do this?  If
not, is that because there is a good reason not to?

Thanks

Matt
