That is exceedingly clever of James to have figured that out..
Programs like scalepack2mtz and truncate simply convert the input files and
preserve the same order and indices - for some people this seemed a GOOD
THING.
If you follow TRUNCATE by a FreeR assignment task, which I presumes is the
norm, then the input data IS sorted, and converted to the standard
asymmetric unit.
