Hello Freesurfer People,
Below is the error that I have been receiving after running a recon-all.
There seems to be a problem in the normalization stage.
I checked the orig.mgz and the transform.xfm, and both seem to be
reasonable. 
I was hoping for some guidance/expert advice for how to precede from here.  
I have not tried to add control points as I am fairly novice to freesurfer
and not quite sure how to complete this task. 

Thank you for any advise you are able to give,
Cheers,
Erica

mri_watershed Error: 
Problem in the COG calculation:
T1.mgz may not contain properly normalized white-matter.
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.
