A draft extension of the BIDS standard proposes a standardized representation of event transformations (e.g., scaling event amplitudes, dummy-coding continuous predictors into discrete ones, etc.). The pybids library contains various tools for manipulating BIDS projects. In this project, we'll continue ongoing work to implement the draft transformations spec in pybids so as to enable fully automated application of complex transformations encoded in a compact JSON spec. This will allow researchers to create much more sophisticated design matrices by manipulating behavioral data and/or event files without having to write any new code.
