Ok, the text for that error message is misleading. In your case DM
complains about missing columns - that's because your eden-unique.mtz
files is corrupt (see below). Could you please remove the
eden-unique.* files?

NOTE: the values you use in your normal CCP4 setup file are not used
by SHARP. Furthermore, the 'default' CCP4 policy of setting scratch
directories to something like /tmp/$USER (and creating this directory
if it doesn't exist) is not used. 

SHARP uses it's own (cut-down) version of a CCP4 setup script. Have a
look in the various $BDG_home/machines/*/ccp4.setup files (e.g. 'grep
BINSORT_SCR $BDG_home/machines/*/ccp4.setup'): this is the value it is
using. If this points to a non-existing directory (e.g. /tmp/chris) it
will complain. Make sure that it points to a directory that will
ALWAYS exist!

Cheers

Clemens
