# Sherlock

Naturalistic fMRI dataset: 16 subjects watched ~50 minutes of *Sherlock* across
two scanning runs (Part1, Part2) and then verbally recalled the narrative in
the scanner. TR = 1.5 s.

This repo mirrors the fmriprep-preprocessed dataset originally distributed via
DataLad at <https://gin.g-node.org/ljchang/Sherlock>. fmriprep version 1.2.6-1.
