Thank you Michael for this link !

However, it seems that we have to install very precise versions of FSL and Freesurfer.

Once we get fsl-5.0.6 package (http://fsl.fmrib.ox.ac.uk/fsldownloads/oldversions/), how to install this one and which wiki to follow ?

Cheers,

Hi,

I suggest you start with the documentation that accompanies the recently released HCP pipelines.

see

http://www.humanconnectome.org/documentation/HCP-pipelines/

and the link therein to the pipelines on GitHub.

cheers,

Subject: [Freesurfer] HCP pipelines: fMRIVolume --> correction of gradient-nonlinearity-induced distortion

Dear Freesurfer's experts,

I'm trying to follow fMRI Volume pipeline from "The minimal preprocessing pipelines for the Human Connectome Project" (NeuroImage, 2013) on HCP data.

The first step has to be the correction of gradient-nonlinearity-induced distortion. The correction is then done with a customized version of the gradient_nonlin_unwarp package available in FreeSurfer (Jovicich et al., 2006).

I couldn't manage to find this package on internet, the only things I've found is the freesurfer grad_unwarp command and a webpage (https://surfer.nmr.mgh.harvard.edu/fswiki/GradientUnwarping) with no download link...

Where can I find this package and how to use it ?

Many thanks !

Best,
