Import diffractio data from serial macromolecular crystallography
Project description
Calculate statistics of serial MX data from xia2.ssx or CrystFEL and import them to CCP4.
Requirements: ccp4-python from CCP4 8.0 or later (it includes CCTBX)
Example of usage:
$ ccp4-python -m import_serial --hklin 116720-721.lst-asdf-scale.hkl --half-dataset 116720-721.lst-asdf-scale.hkl1 116720-721.lst-asdf-scale.hkl2 --spacegroup P21 --cell 39.4 78.5 48.0 90 97.94 90
$ ccp4-python -m import_serial --hklin 116720-721.lst-asdf-scale.hkl --spacegroup P21 --cell 39.4 78.5 48.0 90 97.94 90 --nbins 20 --dmin 1.65 --project protein --dataset 01
Test data are available in a separate repository: https://github.com/MartinMalyMM/import_serial_test_data
List of all options:
$ ccp4-python -m import_serial --help
usage: ccp4-python -m import_serial [-h] --hklin hklin_file [--spacegroup spacegroup]
[--cell cell_a cell_b cell_c cell_alpha cell_beta cell_gamma]
[--half-dataset hkl1 hkl2] [--project PROJECT]
[--crystal CRYST] [--dataset DATASET] [--dmax D_MAX]
[--dmin D_MIN] [--nbins N_BINS]
Calculate statistics of serial MX data from xia2.ssx or CrystFEL and import them to CCP4
optional arguments:
-h, --help show this help message and exit
--hklin hklin_file, --HKLIN hklin_file
Specify merged mtz file from xia2.ssx or merged hkl
file from CrystFEL
--spacegroup spacegroup
Space group
--cell cell_a cell_b cell_c cell_alpha cell_beta cell_gamma
Unit cell parameters divided by spaces, e.g. 60 50 40
90 90 90
--half-dataset hkl1 hkl2
CrystFEL only: two half-data-set merge files (usually
.hkl1 and .hkl2)
--project PROJECT Project name
--crystal CRYST Crystal name
--dataset DATASET Dataset name
--dmax D_MAX, --lowres D_MAX
Low-resolution cutoff
--dmin D_MIN, --highres D_MIN
High-resolution cutoff
--nbins N_BINS, --nshells N_BINS
Number of resolution bins
