New R-package release 0.2.2, with a small bugfix (fixing NaN values at low Z-scores on imgages with low-smoothness).
From 01.01.2020, the maintanence and developement of pTFCE will be continued in the recently established Predictive Neuroimagiong Laboratory (PNI-lab), lead by Tamas Spisak.
Check out this thread on applying pTFCE on both side of your Z-score map.

Smoothness estimation is now possible based on 4D residual data
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.
