[Freesurfer] Group Analysis

[Larissa Bechtle]

        External Email - Use Caution        

Hi everybody,

 

I ran the following commands which worked out fine for my Group Analysis.

Just like in the wiki-Tutorial available I focused on the thickness of my probands brains at first.  

 

setenv FREESURFER_HOME /Applications/freesurfer

source $FREESURFER_HOME/SetUpFreeSurfer.csh

setenv SUBJECTS_DIR /Users/Forschung/Desktop/Larissa/Gewalt

recon-all -s ab35 –qcache

mris_preproc --fsgd FSGD.fsgd --cache-in thickness.fwhm10.fsaverage --target fsaverage --hemi lh --out lh.gewalt.10.mgh

mri_glmfit --y lh.gewalt.10.mgh --fsgd FSGD.fsgd dods --C lh-Avg-thickness-age-Cor.mtx --surf fsaverage lh --cortex --glmdir leftuncorrected.glmdir

freeview -f $SUBJECTS_DIR/fsaverage/surf/lh.inflated:annot=aparc.annot:overlay=leftuncorrected.glmdir/lh-Avg-thickness-age-Cor/sig.mgh:overlay_threshold=4,5-viewport 3d

 

Currently I am tryig to run the same Group Analysis but now focusing on the volume instead.

Thus I tried to change my commands. I ended up with the same image as in my previous Group Analysis (which focused on  hickness instead of volume) and I dont really get why.

 

I would be very grateful for any support.

 

Best wishes

 

Larissa
