The program output in the terminal window is terse but supposed to be self-explanatory; it can (and most often should) be saved or re-directed to a file. | The program output in the terminal window is terse but supposed to be self-explanatory; it can (and most often should) be saved or re-directed to a file. | ||

If | If XDSCC12 is used with a XDS_ASCII.HKL reflection file (from XDS), 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). Negative numbers indicate a worsening of the overall signal. | ||
If | 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>. 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 enumeration of the INPUT_FILEs - the first of these provides the best data set, and the last one is the worst one. This XSCALE.INP.rename_me can then be edited (i.e. for deleting a few data sets with very negative delta-CC<sub>1/2</sub>), and renamed to XSCALE.INP. | ||
Statistics are given (in resolution shells) for the isomorphous and the anomalous signal. In case of [[SSX]] data (which have few reflections per data set, compared to complete data sets), we typically use nbin of 1 | Statistics are given (in resolution shells) for the isomorphous and the anomalous signal.

To find out about the influence of the ''a'' and ''b'' parameters of the XDS/XSCALE-adjusted error model, you may try the -w option; this assigns the same sigma to all reflections. Likewise, the [https://en.wikipedia.org/wiki/Fisher_transformation Fisher transformation], which serves to make changes in CC<sub>1/2</sub> comparable across resolution ranges, may be switched off for testing purposes, with the -z option. | |||
