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.
Figure 1. pTFCE achieves a significant increase in statistical power in most of the typical fMRI processing scenarios. See the paper for details.
