Re: [Freesurfer] recon from 7T data

Hi Valeria

Jon Polimeni and Andre van der Kouwe put together a specific acquisition and set of preprocessing steps for 7T (mp2rage I believe). You need to account for the transmit inhomogeneities, which are what is causing you to lose the temporal lobes.

Dear Freesurfers,

I am trying to perform the FreeSurfer cortical reconstruction process from my 7 Tesla MEMPRAGE, but am getting very bad results (see first attachment) compared to what I had using the 3 Tesla images (second attachment).

Before launching the "recon-all ....... -all" command, I applied the FreeSurfer Gradient non-linearity correction.

What can have been the problem?

Thank you very much for your help,

Valeria
