BTW, Does the new release of Artemis seem to address the many problems you reported with your multiple data set, multiple feff calculation fits?

It does! I have just performed a couple of tests where I opened old-style project that had "incorrect" FEFF order: data_set1 FEFF0 FEFF1 FEFF4 data_set2 FEFF2 FEFF3 test #1 1. fit the data and saved as another project 2. opened the saved project no missing FEFFs were found nothing changed test#2 1. change data in the project 2. fit and saved as another project 3. opened the saved project again no missing FEFFs were found and no other suspicious behaviour was observed These things did't work before Stanislav
