[Freesurfer] Longitudinal processing clarification

(Questions for all, but maybe more directed towards Martin) I have some questions about manual edits in regard to the longitudinal stream. Based on the current info on the wiki page, it appears that no edits are pushed forward from the cross-sectional (initial) runs of the subject data, as any

Thanks all. The reason to use start FreeSurfer within Matlab would be to, for example, build a kind of integrated GUI able to accomplish DICOM -> Surface Visualization. But, for my case, its not that necessary; running FreeSurfer externally is acceptable. Thanks again for your help, Raghav O

Hi Raghav, yes, people have done visualization of surfaces in matlab, maybe Thomas (ccd) can comment. As for 2, I'm not sure I understand what you mean. Why would you need to run freesurfer from within matlab? I guess you could use eval to run recon-all if you had to, but I wouldn't think you w

Hi all, I am working on a project that aims to: (1) Use an MRI image, skullstrip and convert the brain volume to a surface (2) Import that surface onto Matlab and visualize it there. (3) On top of that surface in Matlab, add pictures of electrodes as well as 3D "heat maps" of neural activity.

Thank you all for the very good and detailed advice. We reran our cluster-wise correction after lowering the initial p-value (the one which is applied to the T-maps) to 0.01 or 0.001. Interestingly we then get the very same blob like in the FDR controlled approach (supramarginal gyrus). However,

its possible to do 1). see the 'ROI Analysis' and 'Group Analysis' tutorials under: http://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial although doing this seems like 'double-dipping', or 'circular analysis'. 2) is possible, as it seems like an extension of 1). n. On Sun, 2010-01-31 at 14
