FreeSurfer Maintenance (FSM) Grant Data Release
Contents
Introduction
The NIH awared the FreeSurfer Maintenance (FSM) Grant (R01EB023281) to support the development of FreeSurfer. Part of this grant funded a data acquistion. This page provides links to the data as well as documentation about the data. The data contains "standard" T1w anatomical scans plus other modalities, including T2w, multiecho FLASH, MP2RAGE, and diffusion.
Data Download
A tarball of the version 1 release can be found here can be downloaded (17GB). The tarball has 33 subjects. The data have been anonymized and defaced with MiDeFace.
Scan Summary
Each case will have the following files. See the scan protocol for more info.
