RE: Errors in T1 bricks and demos
Hi
Ursula,Thanks for sending me the images. I just had a quick look at
it. This sequence is obviously not a "standard" sequence such as
those used in fMRI studies. The tools currently available in NIAK
are geared towards processing of fMRI, and are not meant as
multi-purpose T1 analysis tools. Having said that, your scans look
like an extreme case of a problem I have observed from time to time
in T1 images acquired in standard fMRI protocols : massive hyper
signal outside of the brain. I'd like to have a version of the algo
which would be robust to that. For your project, I actually
think that SPM and FSL are likely to fail as well on those images
(I may be wrong). I you *need* those brain masks asap, just draw
them manually. I recommend ITK SNAP for this task:http://www.nitrc.org/projects/itk-snapI'll
keep you posted,Pierre
