OVERLAPMAP will do this, but you need to calculate a "label map" with
SFALL first and provide that to OVERLAPMAP as "mapin3", as MW and others
have pointed out already.
RTFM:

Dear Eleanor:
Yes, this is something I want to do (RSR and CC). But I just want to do
the calculation based on a group of residues or atoms, and it seems
OVERLAPMAP doesn't do it, so I think I have to find other ways.

mapdump does this if you select the right flags. But as Ian says you
will get a LOT of numbers. You dont say why you want this information,
but if it is to find the electron density at an atom site overlapmap
will do that if you ask for "real space rfactor"

Hi,
I wanted to convert a binary ccp4 map file to a readable format so that
I
can retrieve the electron density at each real space grid point. Just
tried MAPTONA4 and MAPEXCHANGE, but the resulting ascii file are not
readable, and I didn't find any documentataion about how to read them.
Could somebody give me any hint? Thanks a lot!
Best Regards, Hailiang
