Probabilistic Treshold-free Cluster Enhancement

Welcome to the wiki pages of pTFCE!

pTFCE (probabilistic TFCE) is a cluster-enahncement method to improve detectability of neuroimaging signal. It performs topology-based belief boosting by integrating cluster information into voxel-wise statistical inference.
