Hi Haben,
If you have reduced scattering profiles as .dat files (3 column text files of q, I(q), and uncertainty) from B21 then you shouldn’t need a configuration file, those are only needed if you want to reduce images to the 1D scattering profiles.
If you have .dat files you should be able to load them in as described here:
Let me know if that helps, or if you actually do have image files you need to reduce and we can discuss further.
All the best.
