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.

​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
Like I said, I would really need to know more about what you are trying to do.
Peace,
Matt.

That all make sense -- thanks a lot, Matt. We will use the applywarp
output. Concatenation of tarnsforms is also something we do.
