Hi Krista,
I believe the v?.thresh labels are thresholded at p=0.8.  This threshold is based on comparisons of actual and predicted V1 boundary with an
independent dataset.

Hi all,
Can anyone provide information regarding how v1.thresh.label and v2.thresh.label that are automatically implemented
in FreeSurfer are thresholded? 

Thanks!
Krista
