Xds

XDS is the main program of the XDS program package. Binaries are available for Linux, SGI, Alpha and Mac platforms.

XDS is run simply using

xds

for the single-processor version, and

xds_par

for the parallel version of the program. Several instances of the single or parallel version of the program can be run at the same time on the same dataset (see MAXIMUM_NUMBER_OF_JOBS= keyword).

XDS reads the 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
• INIT
• COLSPOT
• IDXREF
• DEFPIX
• INTEGRATE
• CORRECT

(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.
