Dear Todd, if you processed your data with XDS, you can provide the REFERENCE_DATA_SET there. Otherwise pointless would also do what you want and in addition aimless lists the anomalous CC of all the pairs if you give each file a separate name in pointless.

Hello all-
I am trying to merge a few partial Se datasets. I am certain that I will have to reindex one or more to make sure that + and - reflections are not jumbled up. Can someone confirm that xtriage take this into account in suggesting to reindex one dataset in relation to a reference dataset? ie. does it use something like maximizing the anomalous signal in suggesting whether or not reindexing is necessary? I think the below suggests as much but I wanted confirmation:
Automatic re-indexing For each data set supplied (other than the first data set given), all possible re-indexing matrices are derived as described by Grosse-Kunstleve et al. (2005). Each data set isautomatically re-indexed using the matrix that maximizes the correlation of amplitudes
Have a good weekend. -Todd
My Example: Reference analyses The following reindexing operators have been found:
------------------------------------------------- | Operator | Correlation | matches (%) | choice | ------------------------------------------------- | -k,h,l | 0.874 | 70.1 | <--- | | h,k,l | 0.032 | 76.7 | | -------------------------------------------------
If the data is reindexed with operator (-k,h,l), the correlation of the intensities to the reference data is maximized. sx205b_anom.sca This can be done for instance with: phenix.reflection_file_converter sx205b_anom.sca --change_of_basis="-k,h,l"
