Use this skill when writing code that uses the pynapple Python package for neurophysiology data analysis. Covers core data structures (Ts, Tsd, TsdFrame, TsdTensor, TsGroup, IntervalSet), time series manipulation (restrict, count, smooth, interpolate, bin_average, derivative), metadata filtering, tuning curves, Bayesian and template decoding, signal processing (filtering, wavelets), correlograms, and perievent analysis. Use when the user mentions pynapple, nap, spike time analysis, time series with IntervalSet, or neuroscience data wrangling.
