[http://xds.mpimf-heidelberg.mpg.de/ XDS] is the main program of the [[Main Page|XDS program package]]. Binaries are available for Linux and Mac platforms. | |||
XDS reads the user-supplied file [[XDS.INP]] which contains the keywords and parameters for a run of the program. To reduce a dataset, it goes through the steps ("JOB"s) | |||
* [[XYCORR]] : setup of spatial correction tables if required | |||
* [[INIT]] : calculate gain of detector and initial background table | |||
* [[COLSPOT]] : find strong reflections for indexing on one or more frames | |||
* [[IDXREF]] : index strong reflections in known cell, or supply info about possible cells | |||
* [[DEFPIX]] : define parts of detector that should be used for intensity integration | |||
* [[INTEGRATE]]: go through dataset and integrate (= calculate intensities of) all reflections | |||
* [[CORRECT]] : scale symmetry-related reflections and print out statistics (file [[CORRECT.LP]]) | |||
(additional, optional JOBs are [[XPLAN]] and [[DIRB]]). | |||
Each step writes a logfile with a name corresponding to the name of the step, with ".LP" appended. | |||

To speed up data reduction even further, several instances of the single or parallel version of the program can be run at the same time on parts of the ''same dataset'' (see MAXIMUM_NUMBER_OF_JOBS= keyword in [[XDS.INP]]). | ||
