The coordinates represent the peak of a significant cluster (alpha < 0.01), only for rPar.
That means there should be a correlation between individual reaction times, and individual connectivity values, in that voxel (and cluster)
That's not the case. Extracting individuals values (from input buckets) from that voxel (or cluster) and correlating with reaction times does not give significant results.
But the same analysis works fine for the peak voxel [16.5 -28.5 50.5] in rFro2, which show this consistency...
Maybe I wasn't clear in what I was correlating, I apologize. Hope now is clearer
Thank you
