Raw data

  • Available in Zenodo
  • EIGER X 9M detector, 5×5 μm2 beam, 1 Å wavelength, 160.0 mm camera length
  • 5°/dataset, 1°/frame (shutterless)
  • 5GQM: 20 datasets collected manually from one cryoloop
    • I23, a= 103.42 Å
  • 5GQN: 184 datasets collected automatically (ZOO) from two cryoloops
    • I23, a= 103.32 Å

How data were processed in the original paper

Processing of individual datasets

GUI command 'kamo' was used by default parameters, that is, XDS (ver. Oct 15, 2015) was used for integration and no prior crystal information was employed.

All 20 datasets of 5GQM were processed, while 155 out of 184 datasets of 5GQN were processed.

Merging

As there were a number of samples, the automatic merging command kamo.auto_multi_merge was used.

First, a CSV file like below was prepared and saved as targets.csv.

topdir,name
/foo/_kamoproc/CPS1963/01,WT in vivo
/foo/_kamoproc/Auto/abe-CPS1963-05,Del3 PhC in vivo
/foo/_kamoproc/Auto/abe-CPS1963-06,Del3 PhC in vivo
# omitted other sample information not described here

Then, the following script was executed (NOTE that command-line arguments here may not be valid in the current version).

kamo.auto_multi_merge \
  csv=targets.csv \
  workdir=$PWD \
  prefix=merge_ \
  postrefine=False \
  reference=2oh6.mtz \
  merge.d_min_start=1.4 \
  merge.clustering=cc \
  merge.cc_clustering.min_acmpl=90 \
  merge.cc_clustering.min_aredun=2 \
  merge.anomalous=false \
  batch.engine=sge \
  merge.batch.par_run=merging \

This script performed resolution of indexing ambiguity using 2oh6 data, hierarchical clustering based on intensity correlation, and merging with outlier rejections for each cluster with expected completeness>90% and redundancy>2, and repeat the procedure by cutting resolution (starting from 1.4 Å).

And there were:

  • merge_WT_in_vivo/cc_1.68A_final
  • merge_Del3_PhC_in_vivo/cc_1.55A_final

from which the result having largest CC1/2 was chosen:

  • merge_WT_in_vivo/cc_1.68A_final/cluster_0013/run_01/ (14 datasets merged)
