There is no code in FSL that will do a q-space or DSI reconstruction. I don't think there is any freeware around that will do this. You may have to write your own code in matlab - The reconstruction will basically be a 3d fourier transform, but you will have to do quite a lot of playing with the outpu to get itin a useful and visualisable form - you might be able to email some of the guys at MGH (e.g. Van wedeen?) to see if they will give you some code. cheers T On 6 Jul 2007, at 19:28, Touko K. wrote: > Hi! > > I was just wondering if it's possible to use FSL to q-space > analysis of diffusion data and if it's possible how should I start? > I've never used FSL anyway and now I should make some analysis from > diffusion data.
