Dear all, I would like to merge two datasets containing anomalous signal. If have done so earlier for native data within phenix in the reflections editor by selecting the arrays corresponding to FP and SIGFP and then running the program. However when I try to do so for the anomalous datasets it writes FP SIGFP and FP2 SIGFP2 instead or merging them, so it does with the anomalous signal... so I guess I have basically only one file containing two datasets but not a merged dataset. How can I solve it? Would it be possible, on the other hand, to merge a dataset with anomalous signal with a native one? The intention behind is to extend the resolution to the one of the native data.
