T2w in place of T1w during preprocessing


I’ve got a subject’s data where there is no T1w image, but instead there is a T2w. Am I correct in assuming that fmriprep can’t use the T2w image as a replacement for the T1w image in the anatomical portion of the pipeline?


Yes, that is correct - at least 1 T1w image is needed for fmriprep to run.
