Other cWB flavors

cWB exists in several flavors. PycWB is a new modular framework written in Python that retains the original cWB algorithm while improving flexibility, usability, and extensibility. It provides a Python-based interface, an improved injection infrastructure, and a streamlined post-production workflow; the pipeline is organized into modular stages, so users can modify existing components or add new ones without affecting the rest of the workflow. PycWB is open-source.

In parallel, a branch known as cWB-XP is being developed. Unlike pycWB, cWB-XP keeps the ROOT/C++ framework but modifies the core algorithm: the Wilson–Daubechies–Meyer (WDM) wavelet transform is replaced by the multi-resolution WaveScan transform based on Gabor wavelets, and a cross-power (XP) statistic (Klimenko 2022) is used alongside the excess-power statistic. cWB-XP is currently not open-source.
