Re: [Freesurfer] fsfast read_surf bug

Hi Joe, that is an overlay for a surface, not a surface itself. It just has a value for each vertex. A surface has geometry and neighborhood info. Try using MRIread.m instead. doug On 7/14/13 3:57 PM, Joseph Dien wrote: I've been trying to use the read_surf.m Matlab function included in the M

2013-07-14 Thread Frédéric Briend
Dear FreeSurfer team, Firstall, thanks a lot to your great contribution in the neuroscientific and the free software world. I would like to know if is it possible to make a plot activation foci (i.e. example by PySurfer: http://pysurfer.github.io/auto_examples/plot_foci.html) by FreeSurfer

Hi Jeff, If you run recon-all on your individual subjects, it would have automatically generate the registration files (?h.sphere.reg) to fsaverage. Doug's reply about mri_surf2surf should work. You just need to apply mri_surf2surf separately for the left and right annots. Cheers, Thomas On Sun

Dear Doug & Bruce, It's indeed a confusing situation. What it boils down to is: - I scanned the polar angle session and the eccentricity session on different days - I had defined V1-3 already based on the polar angle session before scanning eccentricity - All data from the polar angle session wer

[Freesurfer] motion dependent resolution: bbr vs flt

2013-07-14 Thread Roschinski, Benjamin
Dear freesurfer experts and users, we visualize white matter tracts of anorexia nervosa patients which are characterized by more movements in mri studies. We have the impression that we get worser TRACULA outputs by using bbregister than flt. Could it be possible that bbregister needs a higher r

[Freesurfer] Measure outer surface area

2013-07-14 Thread Irene Altarelli
Dear all, how can I measure the surface area of the outer surface computed to calculate lgi? I've tried mris_anatomical_stats subject lh pial-outer-smoothed but that doesn't work (since it doesn't match lh.pial). Any idea would be greatly appreciated. Thank you, Irene _
