Different scan direction




Can fmriprep handle different scan directions?

i.e.- if some of the scans are top-down and some are vice versa-
how should this be handled?



By top-down and vice-versa, you are referring to ascending/descending slice orderings? If you’re looking to use slice-timing correction, you should make sure that you have valid SliceTiming metadata for each file. But beyond that, there should be no issues with handling such images.
