[Freesurfer] freesurfer installation (fail)

2012-03-14 Thread Daniël Höhle
Hello there, I''ve tried a couple installations of FreeSurfer as listed on the website. Though there seems to be a problem. Both linux tarballs seem to be designed for centos4, though that version is not supported anymore, so downloading is a pain, and accessing packages is out of the question.

[Freesurfer] Freesurfer: surf2vol?

2012-03-14 Thread Florsek
Dear all, we have performed a cluster analysis in Qdec and found a significant vertex-cluster after correction for multiple testing using the Monte Carlo simulation. Our aim is to map the vertices to an atlas which is different from that of Desikan. To do that we need the volume-based information

Use mri_binarize with an input and a mask. If you want the number of voxels in the intersection, then use the --count option. doug Miranka Wirth wrote: > Dear freesurfers, > > how can I compute the intersection between binarized masks? > > Thank you for your support, > Miranka > > ---

Fatima, You might have an older bundle of the data. I've confirmed that the current tarball contains the aseg.stats file that you noticed is missing. It was missing at one point several months ago. You dont need to download the tarball again if you dont want to. Instead, you can recreate the st

[Freesurfer] TRACULA: isn't the posterior distribution a probability?

2012-03-14 Thread Juke Cha
Dear Dr. Yendiki and TRACULA experts, I was wondering what the unit of posterior distributions of reconstructed paths? By looking at the intensities, it ranges from 0 to ~150. I thought this is supposed to be a probability, but it's not? If it's in arbitrary unit, should I z-score them in order to

If you have the col row and slice of a voxel, then mni305xyz = X*S*crs where crs = [col row slice 1]' X = matrix from subject/mri/transforms/talairach.xfm S = matrix from "mri_info --vox2ras orig.mgz" Note that these coordinates are for MNI305 space. doug Tianyi Qian wrote: > Dear Freesurfer exper
