## History & Acknowledgments

This folder is a snapshot of the data historically associated with the `NAMIC: Brain Mutlimodality` collection served from `[http://insight-journal.org/midas/collection/view/190`](http://insight-journal.org/midas/collection/view/190).

Datasets originally published in February 2010 by Sylvain Bouix, Doug Terry and Marek Kubicki from Harvard.

## Description

There are 20 cases; ten are Normal Controls and ten are Schizophrenic.
In each case folder, there are 10 files, described here:

* 01###-t1w.nrrd is the weighted T1 scan.
* 01###-t2w.nrrd is the weighted T2 scan.
* 01###-t2w_mask.nrrd is a labelmap of the ICC based on the T2.
* 000008.SER-anon.tgz is the fMRI scan (zipped tar ball) - - Note: there in no fMRI scan for case01073
* 01###-dwi.nhdr (references 01###-dwi.raw.gz) is the raw DTI scan.
* 01###-dwi-filt-Ed.nhdr (references 01###-dwi-filt-Ed.raw.gz) is the dwi scan after noise filtering and eddy current and head motion correction.
* brainmask.mgz is a T1 grayscale image that has the skull & dura-matter stripped.
* aparc+aseg.mgz is a freesurfer segmentation of the t1w image.

Data Description:

* Structural MRI (sMRI) For the Structural MRI volume measurements, images will be acquired using a 3T GE) at BWH in Boston, MA. We will use an 8 Channel coil in order to perform parallel imaging using ASSET (Array Spatial Sensitivity Encoding techniques, GE) with a SENSE-factor (speed-up) of 2. The structural MRI acquisition protocol will include two MRI pulse sequences. The first results in contiguous spoiled gradient-recalled acquisition (fastSPGR) with the following parameters; TR=7.4ms, TE=3ms, TI=600, 10 degree flip angle, 25.6cm^2 field of view, matrix=256x256. The voxel dimensions are 1x1x1 mm. The second- XETA (eXtended Echo Train Acquisition) produces a series of contiguous T2-weighted images (TR=2500ms, TE=80ms, 25.6 cm^2 field of view, 1 mm slice thickness). Voxel dimensions are 1x1x1 mm.

* Diffusion Tensor Imaging (DTI) DTI scans will be acquired on a 3 Tesla GE system using an echo planar imaging (EPI) DTI Tensor sequence. We will use a double echo option to reduce eddy-current related distortions (Heid 2000; Alexander 1997). To reduce impact of EPI spatial distortion, we will use an 8 Channel coil that will allow us to perform parallel imaging using ASSET (Array Spatial Sensitivity Encoding Techniques, GE) with a SENSE-factor (speed-up) of 2. We will acquire 51 directions with b=*9*00, 8 baseline scans with b=0. The following scan parameters will be used: TR 17000 ms, TE 78 ms, FOV 24 cm, 144x144 encoding steps, 1.7 mm slice thickness. We will acquire 85 axial slices parallel to the AC-PC line covering the whole brain. In addition, Bo field inhomogeneity maps will be collected.

* Resting State fMRI This sequence is an additional EPI BOLD sequence that requires Brain Wave software, available only with 8 Channel coil. It's a resting state fMRI that was 10 minutes long, and contains 200 repetitions of a high resolution EPI scan (96x96 in plane, 3mm thickness, TR-3000 ms, TE=30, 39 slices, ASSETT). Subjects closed their eyes and rested while the magnet was running.
