xia2 command syntax: now changed

As per previous post the command syntax change branch has now been merged, if you get your xia2 from git your next git pull will be a big one and you may find e.g. -resolution / -atom etc don't work any more... The functionality is still there however, you just need to use atom=Se (say) or anomalous=true, d_min=1.6... full documentation will follow of the changes.

The pipeline options -3d. etc remain however are now deprecated but still work, you will get a note saying "please use pipeline=3d"

Please if you find any bugs as a side-effect of this contact or add an issue at

Please be aware: changing command syntax

At the moment we use a mix of command syntax, some using Phil (i.e. unit_cell=a,b,c,al,be,ga) and some using legacy arguments: we plan to completely remove the latter in favour of the former, see

with the intention that using xia2 in an automated environment is more straightforward and making it much simpler to automatically maintain much more complete documentation of all the options.

This will be a feature of the 1.3 release of DIALS.
