SVN xia2 now working with newest XDS

At least, in most circumstances - any problems do please get in touch!

Moving targets

Two recent issues to arise:

 - using xia2 with new phenix builds: nightly builds as of last night should now work - dxtbx was not being compiled as a module. Using updated cctbx recent build was a useful workaround though that was also briefly broken for Rigaku A200 instruments (now fixed)

 - new XDS - format for XPARM file has changed so xia2 now chokes - this one may not be as straightforward to fix, but work ongoing

Making xia2 from svn actually *work*

This requires a relatively recent version of cctbx (some bits of xia2 were moved into cctbx.)

Go to

http://cci.lbl.gov/cctbx_build/

Select "show unreleased builds"; select *green* link like YEAR_MO_DY_NNNN (e.,g. 2013_05_07_0005 today) then download the appropriate build for your machine.

This should be automated as part of a xia2 download script: I will look into it. Please be sure to source the cctbx setup file after CCP4 as CCP4 distribute an old version...

Installing xia2 from subversion (latest update)

Assumes you have xia2, cctbx, optionally Labelit and XDS set up in your PATH... here is a bash script which will install xia2 and make you a setup file:


#!/bin/sh

svn checkout https://svn.code.sf.net/p/xia2/code/trunk/xia2
cd xia2
echo "#!/bin/bash" > ../xia2.sh
echo "export XIA2_ROOT=`pwd`" >> ../xia2.sh
echo ". \${XIA2_ROOT}/setup.sh" >> ../xia2.sh

just copy this to a file of your choice (say install-xia2.sh) and then run bash install-xia2.sh where you want xia2 to be installed. Sourcing xia2.sh (which is auto generated) will then set up xia2.

Nightly build needed: will be on the way

In many cases people wait a while before features become available in xia2 because of the slow release schedule. I am looking into producing a nightly build downloadable from the usual CCP4 home, with test logs.

This may be a better way to keep up with the "bleeding edge" of xia2 than using svn...
