Plot gallery

Every panel below was calculated and drawn by Circadian Workbench from one seeded, redistributable example set. Think of it as a showroom wired to the real engine: these are not hand-drawn mock-ups.

Each linked analysis page gives the exact call, every argument, the governing equation, output interpretation, and limitations. Each plot folder carries exact result data, a standalone producer, source hashes, editable SVG, and a browser preview.

Preprocessing

Common detrending methods applied to one trace Choose a detrending method Which slow-background correction matches this trace? All normalisation methods applied to one trace Choose a normalisation method Which shared vertical scale answers the comparison?

Period and rhythm

Compare period estimates example Compare period estimates Which period estimate should I trust? Test rhythmicity example Test rhythmicity Is this series rhythmic under JTK or eJTK? Detect two circadian components example Detect two circadian components Is this record carrying two circadian rhythms at once? Track phase and period example Track phase and period Does phase or period drift through the recording?

Entrainment and perturbation

Fit a phase response curve example Fit a phase response curve How does stimulus timing change the clock? Measure a dose response example Measure a dose response How much stimulus does it take to move the clock? Measure phase angle example Measure phase angle How far is the daily marker from the zeitgeber transition? Measure re-entrainment example Measure re-entrainment How quickly did the clock catch a shifted schedule? Measure acute masking example Measure acute masking Did a light pulse change activity while it was present?

Sleep and environment

Score immobility sleep example Score immobility sleep How much sustained immobility sleep occurred, and when? Measure food anticipation example Measure food anticipation Did activity rise before the declared mealtime? Find ultradian rhythms example Find ultradian rhythms Is there a repeatable rhythm faster than one day? Test temperature compensation example Test temperature compensation Does period remain stable across temperature?

Within-recording population

Compare measurement channels example Compare measurement channels Do two channels keep the same period and lag? Measure population synchrony example Measure population synchrony Did the population damp because cells desynchronised? Map phase across space example Map phase across space Is phase graded across the tissue? Measure pairwise coupling example Measure pairwise coupling How far does one trace lead another, and is the lag stable? Separate phase and period dispersion example Separate phase and period dispersion Did coherence fall because periods diverged or phases spread?

Prediction and design

Plan sample size example Plan sample size How many independent units are needed for the chosen effect? Predict the entrainment range example Predict the entrainment range Which zeitgeber periods can this phase response curve entrain to? Predict re-entrainment example Predict re-entrainment How many cycles should a schedule shift take? Fit the two-process sleep model example Fit the two-process sleep model Which sleep-pressure parameters are supported by this record? Predict sleep pressure example Predict sleep pressure What does the fitted sleep model predict under a new schedule?

Validation examples

Known-answer examples separately check hand-counted imports, an analytic phase-response curve, and the constant-period Q10 identity. A gallery figure demonstrates output shape; only an entry labelled independent PASS is external validation.
