If you want to import integrated files from XDS into Pointless and Aimless, you 
should use Pointless to do the conversion rather than the older program Combat. 
This is what is done if you use the ccp4i interface task "Symmetry, Scale, 
Merge (Aimless)"

Combat wrongly fills in the FRACTIONCALC column in the unmerged MTZ file with 
ITEM_PEAK/100 which is different, and then by default Aimless will reject all 
observations which have a value of less than 95 in this field (unlike Scala 
which will accept them, as they are flagged as fully-recorded)

If you _must_ use Combat (but why?), then you should add the line

partials test 0.1 1.05  # accept data mislabelled by COMBAT

to your script for Aimless (also possible in ccp4i)

Pointless can read one or more MTZ files, XDS files (XDS_ASCII.HKL or 
INTEGRATE.HKL), and Saint files (.raw) and write an MTZ file suitable for 
Aimless

Also Scalepack files and ShelX files: these are not normally suitable for 
scaling, but may be used for statistical analysis in Aimless with SCALES 
CONSTANT or ONLYMERGE options

Combat may be useful for conversion of other file formats not read by 
Pointless, but caveat emptor
