Dear Jordi, for XDS/XSCALE users, there is XDSCC12 (see https://wiki.uni-konstanz.de/xds/index.php/Xdscc12 ).
It is integrated in XDSGUI (statistics tab) where it shows, for a single XDS_ASCII.HKL, how much batches of the run contribute towards CC1/2 of the dataset, i.e. what there delta-CC1/2 is. This e.g. allows to see where radiation damage sets in. For use with merging of datasets, you create a XSCALE.INP with OUTPUT_FILE=WHATEVERNAME.HKL INPUT_FILE=/some/where/first/XDS_ASCII.HKL INPUT_FILE=/some/where/econd/XDS_ASCII.HKL INPUT_FILE=/some/where/third/XDS_ASCII.HKL ... (as many INPUT_FILEs as you want) Then you just run xscale_par and obtain XSCALE.LP and WHATEVERNAME.HKL (and a bunch of control files; if you are not interested in these, there are options that prevent their creation). Finally, you run xdscc12 WHATEVERNAME.HKL | tee XDSCC12.LP and it will calculate the delta-CC1/2 statistics of each dataset, for each resolution shell. It does this for the isomorphous signal (which is what you ask about), and for the anomalous signal (delta-CC1/2ano). There are options that modify the action and output of the program; you see them in the XDSwiki article or when you run with the -h option. What should make its use easy is that XDSCC12 writes a file XSCALE.INP_rename_me that has the format of XSCALE.INP, but with the INPUT_FILE lines sorted by the quality of the datasets i.e. by their delta-CC1/2 . I'd read and edit XSCALE.INP_rename_me, remove the last one if it has a negative delta-CC1/2 , then rename to XSCALE.INP, and re-run xscale_par . If you have many datasets, this can be iterated; I hope you get the idea. If you have questions, pls get back. Hope this helps, Kay On Fri, 21 Jun 2024 15:15:34 +0000, Jordi Benach <benach_jo...@lilly.com> wrote: >Dear Everyone, >Suppose you have three or more datasets and would like to choose the best >combination to merge and produce a higher quality dataset.
