Dear Marina,
Are you running a FEAT analysis on your denoised data?
If so then you can use the original registration and do not
need to do registration directly with the filtered data. This
assumes that the filtered data and the original data are in
the same space (which would be the case for MELODIC
denoising).
All the best,
Mark
