If xdscc12 is used with XDS_ASCII.HKL, the isomorphous delta-CC<sub>1/2</sub> of a batch of frames (width chosen with the -t option) relative to all data is most easily visualized via [[XDSGUI]] (Statistics tab); the delta-CC<sub>1/2-ano</sub> may be plotted with e.g. gnuplot after grepping the relevant lines from the output. | |||
If xdscc12 is used with a XSCALE.HKL generated from multiple datasets, the output lines show the contribution of each dataset toward the total CC<sub>1/2</sub>. Negative numbers indicate a worsening of the overall signal. In this case, the program writes a file called XSCALE.INP.rename_me which shows statistics of delta-CC<sub>1/2</sub> and delta-CC<sub>1/2-ano</sub> values, and has a sorted list on INPUT_FILEs - the first one provides the best data set, and the last one is the worst one. This XSCALE.INP.rename_me can then be edited (i.e. deleting a few data sets with very negative delta-CC<sub>1/2</sub>), and renamed to XSCALE.INP. | |||
