Hello,
If a QDEC analysis returns a certain cluster as being significantly different between the groups (after MC correction) in terms of some measure, which part of this cluster's description should my interpretation of this result be based on: its spatial extent (how it looks when projected onto the template brain, and what your knowledge of brain anatomy makes of that) or the coordinates of its maxima (as reported in the terminal window)?
For instance, my result cluster is labeled as the postcentral gyrus, I guess because that is the parcel that overlaps most with the cluster (or perhaps because that is where the maximum point of the cluster falls?!), but looking at the cluster, it clearly extends into the parietal lobe:
So how does one go about describing this cluster and interpreting the meaning of the effect in a Discussion section? Should I focus on the postcentral gyrus label and link it to other PCG effects in the literature? Or should I instead try to find in the literature maxima coordinates that are similar to what I get here?
Any help much appreciated! --Francesco
