Re: [Freesurfer] data not Surving FDR

2010-10-22 Thread Michael Harms
Hi Mira, If the map you provided is of uncorrected p-values at say p=0.05, then you appear to have just a couple small regions of group differences, so it isn't surprising that after FDR nothing would survive. The result is what it is, and unless you had specific a priori hypotheses regarding re

[Freesurfer] data not Surving FDR

2010-10-22 Thread Mira Michelle Raman
Hi, I have a dataset that seems to have some very nice group differences (please see the graph and qdec image), but they never seem to survive FDR. I noticed when I run the "Set Using FDR", it generates a very high threshold above 5; where as, with some of my other datasets FDR is set much lo

use mri_binarize to set each brain voxel value to the same value (maybe bet does this), then use something like: mri_tesselate mybrainmask.nii.gz 127 mybrainmask.surf where '127' happens to be voxel value used in the binarization. n. On Fri, 2010-10-22 at 15:08 -0600, Alexander Hunold wrote: >

[Freesurfer] Nifti surface to FreeSurfer surface

2010-10-22 Thread Alexander Hunold
Dear experts, I got BEM surfaces out of the BET tool from the FSL package. The surface files are in nifti format (*.nii.gz). Now I wonder if there is any opportunity to convert nifti surfaces to FreeSurfer surface in surf format (*.surf)? I appreciate any hint. Thank you so much in advance.

2010-10-22 Thread Nick Schmansky
the subject 'fsaverage', included in the subjects dir of the distribution, is already registered to talairach space, and it contains the desikan annotations, so you could get the coords from that. you'd have to load it in tksurfer and click on the center vertex of region to get the coord though, a

[Freesurfer] Talairach coordinates for Desikan gyral regions

Hi all, We are trying to depict spatial relations of each of the Desikan et. al (2006) gyral regions in a separate 3-D graph. To do this we need every regions' center Talairach coordinates in common space, not in relation to any particular group or subject. Is there a way to do this
