[Freesurfer] Missing geometry information when converting lh.white using mris_convert

Dear Surfers,

I am trying to create a ROI in freesurfer, and export surface ROI for FSL/ProbtrackX.

I have successfully created label in the template, and use mri_label2label to map the label to different subjects. As suggested by FSL, I use mris_convert to convert the lh.white to Gifti

mris_convert lh.white lh.white.gii echo LMOG.label > listOfAreas.txt label2surf -s lh.white.gii -o lh.LMOG.gii -l listOfAreas.txt

After I failed to do ProbtrackX, I tried to visualize the gii surface in freesurfer, and it tells me:

"Did not find any volume geometry information in the surface"

So, I tried to check the mailing list and tried:

mris_convert -t subj1 lh.white lh.white2.gii

However, it's even worse... [image: Inline image 2]

Red: original lh.white Green: mris_convert -t subj1 lh.white lh.white2.gii Blue: mris_convert lh.white lh.white2.gii

Does anyone successfully used freesurfer surface to do FSL/ProbtrackX？ Any suggestions?

Thanks, Clive
