External Email - Use Caution
Hello all,
I have nifti files with fmri localizer results. I want to use them to
define ROI for source analysis. How can I read these files to MNE, and
convert them from volume to surface?
thanks in advance,
Noa

You probably want to:
1. Use mri\_vol2surf from FreeSurfer
\<[https://surfer.nmr.mgh.harvard.edu/fswiki/mri\_vol2surf>](https://surfer.nmr.mgh.harvard.edu/fswiki/mri_vol2surf>);
2. Read that output with a suitable nibabel function
\<[Neuroimaging in Python — NiBabel 5.1.0 documentation](https://nipy.org/nibabel/reference/nibabel.freesurfer.html#module-nibabel.freesurfer.io>);
3. Decide which surface vertices to use (e.g., by thresholding the NumPy
arrays), and
4. Create a mne.Label \<[https://mne.tools/dev/generated/mne.Label.html>](https://mne.tools/dev/generated/mne.Label.html>); from
them
