Thanks, unfortunately, I am making some mistake but I don´t know where.
First of all I run autorecon1 on my anatomical T1 data (the orig.mgz image is
saved in /usr/local/freesurfer/subjects/anatomical).
Then in the /usr/local/freesurfer/data I run mri
Yes, mri_vol2vol

Hello all,
I want to apply the saved transformation (a transformation matrix 4x4
acquired by registration of an anatomical and a diffusion image) on my
input anatomical mask and change a final FOV
It is valid to compare just the absolute volumes, but it might improve
the results to divide by the ETIV. I would compute the average ETIV and
divide by that. Alternatively, you can compute a relative change
(vol2-vol1)/((vol1+vol2)/2)

Thank you for your response. I have 2 questions.1. I want to extract a binary ROI after group analysis with the command:mri_binarize --i lh.sig.nii.gz --min 9.13 --mask lh.V3A.nii.gz --o lh.ROI.nii.gzfreeview -f $SUBJECTS_DIR/fsaverag

Hi Mr/Mrs
We treated a group of patients. We performed volumetric analysis in
freesurfer before and after treatment.
Is it correct to take volumetric values directly into a paired test?
Or should we perform statistical analysis after dividing all valu
