[Freesurfer] Cluster thresholding

2007-11-28 Thread Alex Fornito
Hi, I have run qdec for a simple contrast comparing thickness across the cortical surface between a patient and control group. Not much survives vertex-wise FDR correction, and I would like to try cluster- based thresholding. I would like to make sure I understand the inputs to the command.

Sarah, Indeed you are correct! The rh9 freesurfer v4.0.1 distribution is missing the fsl tools. I don't know how this happened, as the other dists have it, but I have re-posted freesurfer-Linux-rh9-stable-pub- v4.0.1.tar.gz, containing the fsl tools (actually, a subset of the full fsl distributi

Great! Thanks! My subjects were ran in stable3, so they didn't have the BrainSegVolNotVent measure in the aseg.stats. Rerunning segstats though.. Thanks again! On Wed, 28 Nov 2007, Nick Schmansky wrote: this wiki page has just been created to hold this info: http://surfer.nmr.mgh.harvard.e

This is from mri_segstats --help MEASURES OF BRAIN VOLUME There will be four measures of brain volume in the output summary file: (1) BrainSegNotVent - sum of the volume of the structures identified in the aseg.mgz volume this will include cerebellum but not ventricles, CSF and dura.

Your X server on your virtual Linux image does not appear to have GLX support. If you run 'xdpyino | grep GL' do you see GLX listed? If not, I am not sure what to say as I don't know what virtual machine program you are using. But you need to read up in its docs about how to properly install a

Dear FreeSurfers, I am having a problem viewing in tksurfer: I can only see a sliver of the brain. This sliver will rotate and do everything that tksurfer is supposed to do, but I can't view any more of the brain than a tiny piece of the occipital lobe. I have tried this with several different
