Hi,
My name is Rotem, I'm a PhD. student and recently started to work with freesurfer software (freesurfer-Linux-centos4-stable-pub-v5.1.0). QUESTION For several weeks, I have been trying to operate a script for FA values, with no success, and would really appreciate your help with shading some light regarding the problem and it's solution. I have a data set, after an anatomical segmentation (file is attached, named "Anatomical segmentation for fs", this is the script I'm using for brain anatomical segmentation). What I'm trying to run now is the DTI script, in which I run commands that at least for my understanding spouse to give me at the end a table with all the FA values for each brain region (ROI). The script I'm using to do this is attached and called "DTI_RUN_NEW_FOR_FS". *After running phase 5*, in which a mask file should be created (indeed I have checked and the file is created in the same folder it should be):
fmri4-P67A-D3-B3:/usr/local/freesurfer/subjects> mri_mask /usr/local/freesurfer/subjects/FOLDER_NAME/DTI/fa_FOLDER_NAME.nii /usr/local/freesurfer/subjects/FOLDER_NAME/mri/brainmask.mgz /usr/local/freesurfer/subjects/FOLDER_NAME/DTI/fa_FOLDER_NAME.mask.nii DoAbs = 0 Found 16777216 voxels in mask Writing masked volume to /usr/local/freesurfer/subjects/FOLDER_NAME/DTI/fa_FOLDER_NAME.mask.nii...d one.
*I run phase 6, and then get the following error message:*
fmri4-P67A-D3-B3:/usr/local/freesurfer/subjects> mri_segstats --seg /usr/local/freesurfer/subjects/FOLDER_NAME/mri/wmparc.mgz --ctab $FREESURFER_HOME/FreeSurferColorLUT.txt --i usr/local/freesurfer/subjects/FOLDER_NAME/DTI/fa_FOLDER_NAME.mask.nii --sum /usr/local/freesurfer/subjects/FOLDER_NAME/stats/all_stats_fa_FOLDER_NAME

I think the problem is between phase 5 and 6, and is related to file format (.nii) but don't have a hint regarding what can I do to solve this:( Can someone please write me the correct code line ?
I would really appreciate your kind help since I run out of ideas for solutions.
Thanks in advance,
Rotem
