Thanks, Doug. It works but I am not sure if the values I'm getting are correct. Is this supposed to be reporting the mean cortical thickness of each cluster? I have pasted the output below from the avgwf below. The names of the clusters correspond to the regions from the "summary" text, am I right?
Group lh_fusiform lh_precentral lh_insular lh_precuneus lh_parsorbitalis 1 24.29454 29.53935 14.24736 28.97924 31.54577 1 25.68872 28.26156 17.47828 28.20604 30.38902 2 25.46281 30.75879 19.34943 29.59019 32.0404 2 25.55514 27.23871 17.27937 29.14274 29.75657 Another related question: Is it possible to simply take the mean cortical thickness across the voxels exceeding p<0.001 from the uncorrected sig.mgh? Thanks again! Best Wishes, Elijah
