Hi Edward,
Testing on a Mac OS X system using the relax 3.1.5 DMG file shows that the files are correctly recognised. Maybe there was a mixup during the file loading.
likely
Could you try to loading the data again and seeing if the problem is still there.
it is OK now
Note that the relaxation ID must be different for different data sets!
NOW I understood it
In relax the user can load multiple analysis files with the same ID. This is deliberate as the user may have processed different peaks with different window functions, and hence have a number of Bruker DC or peak lists for one experiment. Or the user may have backbone N, C-alpha or other data from different spectra but which should be analysed simultaneously.
got it! Thanks! Stefano
