Hello James,
You can try the map2map from the SITUS package (

It is possible that the map is just too big. You might run into
"problems" with file I/O in general if it is bigger than 2 GB. If you
have a 64-bit machine with CCP4 completely re-compiled in 64-bit mode,
then it "should" be able to read the large files (but I have not had
much luck with this
Hi James,
I had similar problems with MRC maps. As a solution, a colleague of
mine, working with EM, read the MRC map into SPIDER and saved it as a
CCP4 map. That worked for me. Unfortunately, my colleague is absent for
some time, and I'm still not familiar with EM software. But maybe, you

Hi all-
I'm trying to convert a cryoEM map from FREALIGN for use with various CCP4
programs, or with MAPMAN. Even though the MRC format is derived from the
CCP4 map file format, every program I've tried fails to open it, (except for
Chimera which displays the map but cannot save it to another form
