Mat-file: a single mat-file - ratatlas.m - contains all data, and is structured as follows: DWI: Cell array containing all 13 diffusion weighted images DT: Cell array containing the 6 independent diffusion tensor elements FE: First eigenvectors eigval: Three eigenvalues of the diffusion tensors FA: Fractional anisotropy map FEFA: FE map scaled by the FA map. VDims: Voxel dimensions g: Diffusion gradient directions bval: Diffusion gradient strength labels: Label field T1: T1 image 2. Nifti: all diffusion weighted images, the T1 image, and label field are saved as individual nifti files (DWI_0..13.nii, T1.nii, and labels.nii). Diffusion gradient information has been stored in grad.txt, while the delineated anatomical structures are enumerated in labels.txt. 3. Amira: the label field is also provided in Amira format, labels.am. This file can be used for further segmentation, or (3D) visualization in Amira. 2016-10-11 Population-averaged DTI atlas (nifty) Population-averaged diffusion tensor imaging atlas of the Sprague Dawley rat brain Microscopy, MR, Computational Neuroscience, UA_VLAB licence, Free For Non-Commercial Use Only, NIfTI-1, ASCII, End Users, English, OS Independent, MATLAB http://dev.nitrcce.org/projects/visionlab/, http://http://www.nitrc.org/projects/visionlab/
