[Freesurfer] extract beta values ROI

2012-01-30 Thread Lúcia Garrido
Hello, I'm trying to extract beta values in cortical thickness analysis. For example, if I use qdec to look at the association between cortical thickness and variables A and B, can I extract the vertex-wise parameter estimates corresponding to the association between A and cortical thickness acros

Hello, I've been running Freesurfer v4.0.2 in Debian and now wanted to use a computer that has Red Hat 9 to also run some subjects. Could you let me know if it's possible to download version 4.0.2 for Red Hat? Many thanks, Lucia ___ Freesurfer mailing

[Freesurfer] vertex wise correction for multiple comparisons using permutation

2008-12-04 Thread Lúcia Garrido
Dear Freesurfers, I'd like to correct for multiple comparisons vertex-wise instead of cluster-wise. Is it possible to do this using permutation (and not FDR)? I've seen in an e-mail from last year that the values of maximum statistic stored in the CSD file could be used for this purpose, and I'd b

[Freesurfer] stats in freesurfer

2008-11-20 Thread Lúcia Garrido
Dear all, I have a few questions about stats in freesurfer that I'd be very grateful if you could answer. 1. Is it possible to reduce the search from the whole brain to a smaller region of interest to apply corrections for multiple comparisons? For example, if I'm interested in differences in the

[Freesurfer] volume in freesurfer

2008-11-16 Thread Lúcia Garrido
Hello, I've run recon-all in two groups of subjects using FS version 4.0.2. I want to compare cortical thickness between the two groups, but I'd like to also compare volume maps between groups. I'd like to see how results in FS compare with results from VBM. In the 'measures' available in design

Hello, I'm using Debian and downloaded freesurfer-Linux-centos4-stable-pub-v4.0.2-full.tar.gz. Everything worked fine when I tested the installation with tkmedit and tksurfer. I then ran recon-all -i C04_SS.nii -autorecon1 -s C04_SS and it also finished without errors. But when I ran recon-all -
