[Freesurfer] Visualization FS-FAST results in graphs

2015-04-08 Thread stdp82
Hi list, I'm performing the FS-FAST for functional connectivity analysis on two groups. I'm using tkmedit to visualize the results. Is possible to load a scatter plot which describes the values of each subject for each selected voxel? e.g. I'd like to verify the presence of outliers.Scatter plot

Hi Ri, you can process data with higher resolution than 1mm^3 if you follow the HiResRecon (https://surfer.nmr.mgh.harvard.edu/fswiki/HiResRecon). The changes to the pipeline were done using v5.1, however, this should still work fine. Best, Falk -Ursprüngliche Nachricht- Von: freesurfe

Hi Pedro if you are able to change the acquisition in the future you might try something closer to isotropic, which would let you get the echo time down. Longer TE decreases contrast as it allows some T2* weighting (which is in the opposite contrast direction to T1) to creep in. cheers Bruce

[Freesurfer] longitudinal processing - OS re-installation

Dear FreeSurfers, I use FS v5.3 on Ubuntu 12.04.3 LTS. I am working on a longitudinal study and now I have problems with my machine. It started to work very slowly and it's losing the Internet connection frequently without apparent reason. I believe there's a bug that affects its performance quite

[Freesurfer] question about preprocessing and analysis in FS 4.5 vs FS5

2015-04-08 Thread Katie Bettencourt
I had a question about using different components of Freesurfer 4.5 and Freesurfer 5 in an analysis. We were wondering whether it is possible to do preprocessing in Freesufer 5, but run the analysis on Freesufer 4.5 or whether the output from preprocessing in Freesurfer 5 is not compatible with th

hmmm, looks like it is a bug in the icosahedral supertesselation algorithm we use as it's in the icosahedron too: mris_info --v 0 $FREESURFER_HOME/lib/bem/ic7.tri v 0: (0.0, 0.0, 1.0), 5 nbrs 0: v 40964, dist 0.0 1: v 40962, dist 0.0 2: v 40965, dist 0.0 3: v 40967
