Feel free to make annotations and comments. I have one T2 weighted image (volume 0) and 64 diffusion weighted images (DWI) (volumes 1-64) in a 4D-NIfTI file with 128x128x96 1.5mm isovoxels. Also a T1 image with a good brain extraction (gray matter) with 256^3 1mm isovoxels and a CSF mask. text/html 2010-07-29T16:19:39+02:00 http://windhoff.net/wiki/getfem?rev=1280413179 text/html 2011-07-12T00:23:00+02:00 http://windhoff.net/wiki/guestbook?rev=1310422980 For junk entries please use this Playground Guestbook.
