xia2 with weak pilatus data

Seems like the latest XDS included a big fix for the processing of weak (i.e. background ~ 0) pilatus data - thanks to Tobias Krojer for the heads-up there. This will involve some slight fixes to the xia2 XDS wrappers, so I will bundle these later today.

N.B. this will require installation of latest XDS!

I should also start to think about how to make fixes like this more responsive... ideas anyone?

xia2 questions...

May be worth posting here too:

in case anyone else would find the answers interesting...

Refactoring resolution calculations

Quick update on this. Phase 1 will be to try and get xia2 to better respect the existing resolution criteria - so when it should be I/sigma ~ 2 at the edge, it is! Then after this, refactor the input a little so that the criteria discussed on the mailing list can be assigned through the input or from a preferences file.

This is quite interesting actually. It's shaking things up a little and may end up with things being a little more efficient...
