Hi all.
I'm using Qdec to compare two groups of patients, and I'm wondering why the vertex with the highest p-value in the clusters changes when the threshold is changed? When lowering the threshold, the significant area should increase, but intuitively, the vertex corresponding to the area with the maximum p-value should remain the same inside the cluster? I'm using the Monte Carlo z-simulation method to remove false positive.
