Dear expert,

I obtained “sig.mgh” from resting fMRI data using Freesurfer. Then, I opened the file using tksurfer. I selected vertex 156439 out of 163842 in the file  “sig.mgh”.

In the terminal, there were several coordinates as followings:

Selected vertex 156439 out of 163842

Current -36.76 -22.70 -10.66

orig        -59.96 -33.44 8.59

pial         0.00 0.00 0.00

I have a question for orig “-59.96 -33.44 8.59”. The coordinate (x=59.96 y=-33.44 z=8.59) is in the ~/freesurfer/7.1.1/subjects/fsaverage/mri/orig.mgz, right?

Thanks,

Gwangwon
