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
Error: *************************WATERSHED************************** Sorting... 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.
