Readme.txt for SPM-normalized subjects OHBM 2017 edition

The is the Bravissima human brain major artery database in NIFTI-1 format.

Enclosed are both the individual and group files for 43 out of the 61 subjects
from the original BraVa database. 

To read more about how these were generated, see OHBM poster

--------------------------

Database files included

1) Group Files - Approximate MNI-152 space

 a) BravaDist43.nii.gz - all 58 subject artery locations marked out by intersubject mean 
                        (i.e. how many subjects have an artrey at a voxel) distance for Left
                        and Right (lh & rh) Hemispheres for the Anterior, Middle, 
                        and Posterior Cerebral Arteries (ACA, MCA, PCA).
 b) BravaSplit43.nii.gz - marks artery branch points for all 43 subjects.
 c) BravaInferior43.nii.gz - marks out the Circle of Willis (CoW) and carotid.
 d) BravaLocSide43.nii.gz - where Side = "rh" or "lh", 
                                   and Loc is "ACA", "MCA" or "PCA"
                            marks the approximate distance in mm along the artery starting
                            at the Circle of Willis. 


2) Individual Files: in Brava43Subs.zip in MNI-152 space

a) srcb*.nii - artery branching code for an individual
b) srcd*.nii - distance along artery from the Circle of Willis
c) srcg*.nii - artery locations coded by group (LH or RH ; ACA, MCA, or PCA)
d) srcr*.nii - artery radius at voxel location
e) srcs*.nii - artery branching locations

-------------------------------

Matlab/Octave scripts included

The norman.m script is the primary script by which NIFTI Brava files from the hand
normalization version were normalized using MRA images to MNI_152 space.  There is
a link to the MRA images at the BraVa website http://cng.gmu.edu/brava

You also need to obtain Jimmy Shen's NIFTI toolbox for Matlab to read in the files
(https://www.mathworks.com/matlabcentral/fileexchange/8797-tools-for-nifti-and-analyze-image)
if you wish to execute "norman.m".

You also need a gzip program to zip the files and the SPM8 toolbox to do the normalization.
