They fall under the broader umbrella of *NiPost* workflows, which perform post-processing on BIDS-Derivative datasets. These workflows are designed to work with derivatives from any pipeline that produces BIDS-Derivative-compliant datasets, and are primarily tested against the outputs of pipelines such as `fMRIPrep`_, `ASLPrep`_, and `QSIRecon`_. .. _fMRIPrep: https://fmriprep.org .. _ASLPrep: https://aslprep.readthedocs.io .. _QSIRecon: https://qsirecon.readthedocs.io
