Hi Bruce
Hi James
you could use techniques that compare the whole distribution of
thicknesses across subject populations. You could do a t-test or something
non-parametric like a Kolmogorov-Smirnov or use permutation testing. I'll

All,
I am comparing cortical thickness between subjects with and without mild
traumatic brain injury (mTBI). So far the contrasts in QDEC have not been
significant after correcting for multiple comparisons. I am not necessarily
surprised at this due to
