Hi Brunce,
The T1 files were too big that I couldn’t attach.
When I looked through the T1.mgz, the white matter intensity were only between
70-90 in majority of the area.
Is there any way that I can adjust the intensity?
Kind Regards,
Julia

Make sure it looks reasonable (that there is a brain in there, and the
intensities look ok). You can send it to us if you want

Hi,
What will you be looking in the T1.mgz?
I am quite new to this field so have a very basic understanding of it.
Much appreciated.

Hi,
While running the recon_all, I bumped into this error message below.

Confirm that T1.mgz has enough white-matter voxels of value 110.
If white-matter contains few if any voxels of value 110,
try adding wm control-points to nu.mgz, and re-run recon-all.

Any help would be much appreciated.
