Dear FreeSurfers,
The pctsurfcon calculates the contrast between the white and gray matter using the formula below and saves the output in the ?h.w-g.pct.mgh file, which can be used for analysis.
100*(W-G) pct = --------- 0.5*(W+G)
However, I would like to get separate measures of white and gray matter intensity, as well as a ratio of gray to white matter (as in the Salat 2009 and 2011 Neuroimage papers). How can this be done?
Your help will be greatly appreciated
Nenad
