Hello,<br><br>I am wondering if it is possible to calculate t-values and significance of a whole ROI in qdec, version 1.2.  Right now, I have no problem doing it on a point-by-point basis, but I want to do whole ROI analysis within qdec.  For example, I want to know the p-value of the whole lh_superiorparietal region for the &quot;Does the average thickness differ between HIV and Control?&quot; contrast.<br>

<br>Your help is always appreciated!<br>Mahalo,<br>Jeff<br>
