Dear Freesurferexperts, I still have the Problem because I can not run the the mris-command to estimate the gyrification-index, because Freesurfer is not recognizing Matlab: "ERROR: Matlab is required to run mris_compute_lgi"Im not sure why this is happening? Does someone have an idea??? Im starting Freesurfer as follows: FREESURFER_HOME=/Users/dhirjak/freesurfer source $FREESURFER_HOME/SetUpFreeSurfer.sh (than I get the following output) Dusan-Hirjaks-MacBook-Pro:~ dhirjak$ source $FREESURFER_HOME/SetUpFreeSurfer.sh-------- freesurfer-Darwin-snowleopard-i686-stable-pub-v5.3.0 --------Setting up environment for FreeSurfer/FS-FAST (and FSL)FREESURFER_HOME /Users/dhirjak/freesurferFSFAST_HOME /Users/dhirjak/freesurfer/fsfastFSF_OUTPUT_FORMAT nii.gzSUBJECTS_DIR /Users/dhirjak/MRI/Freesurfer_2MNI_DIR /Users/dhirjak/freesurfer/mniFSL_DIR /Users/dhirjak/fsl export SUBJECTS_DIR=/Users/dhirjak/MRI/Freesurfer In have the following lines in my matlab startup-file: fshome = getenv('FREESURFER_HOME'); fsmatlab = sprintf('%s/matlab',fshome); if (exist(fsmatlab) == 7) path(path,fsmatlab); end clear fshome fsmatlab; fsfasthome = getenv('FSFAST_HOME'); fsfasttoolbox = sprintf('%s/toolbox',fsfasthome); if (exist(fsfasttoolbox) == 7) path(path,fsfasttoolbox); end clear fsfasthome fsfasttoolbox; Thanks!!!

mri_convert error during make_average_subject
by Jonathan Holt 03 Feb '14

03 Feb '14

Hello FS experts, I’m trying to make an average subject and I had an unfortunate error during the mri_convert stage, specifically an mghWrite error. I failed to save the output so I cannot recall the exact details, are there any specific things I should be looking out for to prevent this? best, Jon

Please remember to post to the list. Thanks! You cannot do that with mri_vol2surf.

Create a surf from a special volume?
by Markus Gschwind 03 Feb '14

03 Feb '14

Dear all, I want to create a surface of a partially altered brain T1 (temporal lobe cut away by hand). I figured out that this would be done with mri_vol2surf. This command asks for a register.dat file. I think that I can get it using this command: SUBJECT_DIR=/Users/FREESURFER bbregister --s /mri/brain_T1.mgz --mov /Users/FREESURFER/mri/brain_T1_ins.mgz --reg /FREESURFER/mri/register.dat --t1 --init-spm I well starts calculation, but suddenly stops and complains that there is no brainmask /Users/FREESURFER/mri/brain_T1.mgz/mri/brainmask.mgz which makes somehow no sense as the brainmask is in /Users/FREESURFER/mri/brainmask.mgz of course. But I don't find a option to specify the brainmask in bbregister. What am I doing wrong? Thanks for any help! Markus

Difference between aseg.stats and mri_segstats
by Jonathan Holt 03 Feb '14

03 Feb '14

Hi All, I'm interested in the cerebellar volume on a particular subject and I was wondering why I am seeing a slight difference between the volume listed in aseg.stats and the volume produced by mri_segstats with aseg.mgz as the input. It's a very slight difference, 44452mm^3 vs 45137.7mm^3 (mri_segstats and aseg.stats, respectively) but I am wondering what the reason is and which is more accurate. best, jon
