Nathan,

The significance values displayed are -log10(p), which is easier to remember this way: a value of '2' (as displayed for a vertex in qdec) is p=0.01, a value of '3' is p=0.001, etc.

Hi all,

I've read in the wiki that the heatmap display in qdec is a -log10(p). What is the stat behind this when determining whether the average thickness differs between two groups? Is it a t?
