/data/sub-x

This folder contains the .nii data for a given subject.

Stratifying by session is optional; we do so as for clinical fMRI patients may or may not have repeat scans (potentially years in the future).

We do not include the 'sessions.tsv' file here, which can be used to document information about what was done in each session.
