Hi FreeSurfer team,
After running longitudinal FS, and running
mri_glmfit using files that measured spc, we found clusters
associated with our continuous variable (WMH volume) after
controlling for other covariates. I was wondering though, do
the values found in cache.th13.abs.y.ocn.dat reflect the
change in thickness (as measured by spc) for each subject of
the cluster found to be significantly associated? I read other
posts that it was a value of thickness of each cluster, but I
wasn’t sure if the same was true for a longitudinal analysis
(spc), as the file contains both positive and negative
numbers.
Thanks so much for your help!
