It worth noting the version "2016/4" has a number of bugs that could easily break tests (in particularly related to symmetry operators and H-bonds). http://www.xrayforum.co.uk/viewtopic.php?f=124&t=2761 http://www.xrayforum.co.uk/viewtopic.php?f=122&t=2758 Cheers, Oleg.

I don't understand exactly what Ralf was testing here, but this test dates from the early days of cctbx (2002) and as far as I am aware hasn't caused any problems until now.
CCP4 update 18 actually appears to be distributing an older version of shelxl than update 14, is this correct? Hopefully the guys at CCP4 can shed some light on what the difference in the shelxl versions they are distributing might be. I don't see any mention of shelxl updates at http://www.ccp4.ac.uk/updates/

Hi,
The test
libtbx.python $(libtbx.find_in_repositories cctbx/development/run_shelx.py) P31
works with CCP4 7.0.17, but fails when run with SHELXL from CCP4 7.0.18.
The test apparently involves creating a small random crystal structure, calculating the structure factors and solving the structure using SHELXL. The updated SHELXL version creates deterministic, but slightly different anisotropic temperature factors. I am not sure if this is a problem with the test or with the SHELXL update. Could anybody have a look into that?
