The following script does the same for the input file (first parameter to the script), but also adds a SUFFIX (second parameter) to the columns to better identify the data, and optionally copies the Rfree-flag from a reference mtz-file (third parameter). If the Rfree-flag is NOT named "FreeR_flag" (the default from ccp4i), you can provide its name as fourth parameter. All steps are logged into log-files, temporary files are deleted. The input file should end with .HKL (rather than e.g. .hkl). | |||
The script also sets the resolution to that of the observed data using sftools. Otherwise the resolution of the reference data set might be shown if that is higher. You can call this script 'xds2mtz.sh'. If it is executed without arguments, you get a short usage instruction. | |||
