Hello - can anybody shed light on this mystery:
We need (for PanDDA analysis) a lot of datasets each to have the
complete set of low resolution indices, whether measured or not. (Refmac
adds the estimates as DFc, which is crucial when comparing maps.)
In ccp4, there are two obvious ways to get these indices complete:
* uniqueify
* CAD using the keyword "RESOLUTION FILE 1 999 <highres>" (999 is the
low resolution limit).
Mystifyingly, in ~1% of datasets, one or the other route misses one or
two indices. Our work-around is to go belt-and-braces and run both for
each dataset.
It does however remain a bug. Does anybody have any idea what's
happening? We can send example datasets to any volunteers who want to
fiddle with it.
