It looks like you have the correct understanding of this. One cannot easily apply the gradient nonlinearity effects on the diffusion gradients to the images, as really you need to apply them to the bvals and bvecs. Peace, Matt. From:

[HCP-Users] DTI on HCP data

2017-08-10 Thread Szabolcs David
​Dear HCP Team, I would like to use HCP diffusion data to do some diffusion tensor fitting and subsequently calculate maps of FA, MD, etc. For this I think it would be handy to use the followings: $subject\T1w\Diffusion\bvals $subject\T1w\Diffusion\bvecs $subject\T1w\Diffusion\data.nii.gz We can

Hi Michael, You can access the data via REST calls-- take a look at: https://wiki.humanconnectome.org/display/PublicData/How+To+Access+Subject+Data+via+REST You can also access the data on AWS-- more info on that here:

Elam, thanks very much for the info. I haven't had time to try this, and the user looking for the data has indeed downloaded it in the meantime while on another network. But I'll keep this info for next time. Is there an scp/sftp/rsync route to the data sets? I have a machine on a different

That all make sense -- thanks a lot, Matt. We will use the applywarp output. Concatenation of tarnsforms is also something we do. Sandy On Mon, Aug 7, 2017 at 6:11 PM Glasser, Matthew wrote: > Hi Sandhitsu, > >1. You could take a difference between the two images to see
