This article deals with how to process serial synchrotron crystallography (SSX) data.
The particular data we are processing are artificial and were prepared by James Holton. The files Illuin_microfocus_minimal_00[1-3].tar.bz2 can be downloaded and the data and problem are described on his microfocus challenge page.
The challenges are
- partial data sets: each of the 100 data sets has only 3 frames of 1° oscillation
- strong radiation damage: the crystals decay to about 1/2 within these 3 frames
- the b and c axes are the same length, but the crystals are orthorhombic. This makes it difficult to index them consistently - it is wrong to just merge them, because that yields a pseudo-tetragonal merged data set.
Round 1: processing the data, and determining the space group
In order to be able to merge the data in XSCALE, we must ensure that they are all processed in the same space group, with similar cell parameters. Some exploratory processing (not shown) and averaging of cell parameters reveals that IDXREF finds a primitive lattice with one axis of 38.3 Å, and two with 79.1 Å; angles are 90°. The data go to 1.8 Å; beyond that, the intensities suddenly drop to 0 - presumably because James Holton simulated them only that far. Using the following as the processing script integrate.rc:
#!/bin/bash -f for f in `seq 1 100`; do export OUT=wedge0`printf "%03d" $f` export NAMES="$PWD/Illuin/microfocus/xtal"`printf "%03d" $f`"_1_00\?.img" rm -rf $OUT mkdir $OUT cd $OUT generate_XDS.INP $NAMES sed -i s"/SPOT_RANGE=1 1/SPOT_RANGE=1 3/" XDS.INP sed -i s"/SPACE_GROUP_NUMBER=0/SPACE_GROUP_NUMBER=1/" XDS.INP sed -i s"/UNIT_CELL_CONSTANTS= 70 80 90/UNIT_CELL_CONSTANTS=38.3 79.1 79.1/" XDS.INP sed -i s"/TRUSTED_REGION=0.0 1.2/TRUSTED_REGION=0 1/" XDS.INP sed -i s"/INCLUDE_RESOLUTION_RANGE=50 0/INCLUDE_RESOLUTION_RANGE=99 1.8/" XDS.INP /usr/local/bin/xds_par cd .. done mkdir xscale cd xscale cat >XSCALE.INP <<eof SPACE_GROUP_NUMBER= 1 UNIT_CELL_CONSTANTS= 38.3 79.1 79.1 90 90 90 OUTPUT_FILE=temp.ahkl SAVE_CORRECTION_IMAGES=FALSE FRIEDEL'S_LAW=TRUE eof find $PWD/../wedge* -name XDS_ASCII.HKL | awk '{print "INPUT_FILE=",$0;print "NBATCH=1 CORRECTIONS=ALL"}' >> XSCALE.INP

Analysis with

which is from a lysozyme SSX data collection performed at the SLS; outliers are labelled. In this case, the data are truely tetragonal.)
We must now investigate whether the data have lower than tetragonal symmetry. XSCALEing with

gives a new temp.ahkl, with orthorhombic symmetry.

Using XSCALE.1.INP with its 51 XDS_ASCII.HKL, and FRIEDEL'S_LAW=TRUE, we get

At this point, we run

and find that data sets 1 and 17 are wrongly included in the cloud of 51 data sets. Thus they are removed manually from XSCALE.INP.
After xscale_isocluster -dim 2 -clu 1 ,
coot iso.pdb
now reveals a single cloud:
We then re-run XSCALE with MERGE=TRUE. The resulting reflection output file XSCALE.1.HKL is then used as REFERENCE_DATA_SET for a second round of integration with XDS.

thus we now know the spacegroup.
Round 2: using the REFERENCE_DATA_SET
The processing script integrate.rc is changed a bit, to a) use the REFERENCE_DATA_SET, b) prevent adjustment of variances by CORRECT (this should be done by XSCALE) , c) allow some radiation damage correction in XSCALE:
#!/bin/bash -f for f in `seq 1 100`; do export OUT=wedge0`printf "%03d" $f` export NAMES="$PWD/Illuin/microfocus/xtal"`printf "%03d" $f`"_1_00\?.img" rm -rf $OUT mkdir $OUT cd $OUT generate_XDS.INP $NAMES echo REFERENCE_DATA_SET=../reference.hkl >> XDS.INP echo MINIMUM_I/SIGMA=50 >>XDS.INP sed -i s"/SPOT_RANGE=1 1/SPOT_RANGE=1 3/" XDS.INP sed -i s"/SPACE_GROUP_NUMBER=0/SPACE_GROUP_NUMBER=19/" XDS.INP sed -i s"/UNIT_CELL_CONSTANTS= 70 80 90/UNIT_CELL_CONSTANTS=38.3 79.1 79.1/" XDS.INP sed -i s"/TRUSTED_REGION=0.0 1.2/TRUSTED_REGION=0 1/" XDS.INP sed -i s"/INCLUDE_RESOLUTION_RANGE=50 0/INCLUDE_RESOLUTION_RANGE=99 1.8/" XDS.INP /usr/local/bin/xds_par cd .. done mkdir xscale cd xscale cat >XSCALE.INP <<eof SPACE_GROUP_NUMBER= 19 UNIT_CELL_CONSTANTS= 38.3 79.1 79.1 90 90 90 OUTPUT_FILE=temp.ahkl SAVE_CORRECTION_IMAGES=FALSE eof find $PWD/../wedge* -name XDS_ASCII.HKL | awk '{print "INPUT_FILE=",$0;print "NBATCH=3 CORRECTIONS=ALL"}' >> XSCALE.INP
and we get as XSCALE.LP :

The substructure (locating 4 Se with anom data to 3Å) and structure (198 residues) can now easily be solved with hkl2map:
Further optimization of processing may be possible, but is left as an exercise to the reader.
