Data Processing¶

Generic signal and index manipulation — consecutive runs, chunk detection, interval arithmetic.

When to use which¶

Task	Use
Group contiguous true / equal runs in a vector	`consecutive_runs()`
Find the index of the nearest value	`findclosest()`
Detect chunks (valid vs NaN / flat stretches)	`get_chunks()`
Intersect two sets of time intervals	`interval_intersect()`
Rolling percentile filter	`percentile_filt()`
Slice a signal by a list of `[start end]` intervals	`pick_from_time_segments()`
