Hi Elizabeth, when FS computes a p-value, it computes assuming an unsigned test. When you specify a sign to mri_surfcluster (eg, --sign pos), it recomputes the p-value to take advantage of the signed test (divides the p-value by 2, same as lowing the threshold from 2 to 1.7. So try using 1.7 in

Hi all, We're trying to create labels from a group level sig.mgh file. However, after the labels are created and an annotation file/color table is made, we try to view the sig.mgh file and the annotation file in tksurfer, but they don't extactly overlap, even though they are both configured to the
