xia2 released

xia2 now updated to

Changes since
  • Now report the min, mean, max mosaic spread (according to the program definitions after integration of each sweep.
  • Resolved problems with overriding environment.
  • Added -serial pun for -parallel 1.
  • Allow resolution limit to be assigned on a per-sweep basis.
  • Handled corner case with images 200 - 250 (say) giving REBATCH error.
  • Added full 8-way search for scaling models for 2d pipelines.
  • Partial support for two-theta offset data collection (tested with Rigaku X-ray equipment and Diamond I19 data.)
  • Added -min_images keyword which is helpful when analysing virus data with e.g. 4 images / sweep.
 Downloads in the usual place - please shout if you have any problems!

Used xia2 in a publication? Please let me know!

At some point I'd like to be in the position to get some help with xia2 developments. If such a situation does arise, it would be much easier if I had an indication of how useful the program has been to people. Now I know I didn't help the cause by taking my time to produce a xia2 paper to cite, to I accept that this is very much may fault :o) However I'd really like to hear from you.

Thanks in advance!

Sweeps starting with image 0

As some of you will know, if you put in some data into xia2 with images starting from 0 it may well explode. XDS gives an error, as does REBATCH in the CCP4 suite (which you would expect to be able to renumber the batches!)

So, the easiest thing to do I think is to externally renumber the images. I will therefore write a little python program to do this - watch this space.
