June 2020

New functions

a. Add the plotly sub-module, a set of Plotly functions comprising systole.plotly.plot_raw, systole.plotly.plot_subspaces, systole.plotly.plot_ectopic, systole.plotly.plot_shortLong, systole.plotly.plot_frequency, systole.plotly.plot_nonlinear, systole.plotly.plot_timedomain.
b. Add plotly.utils.simulate_rr(), for random RR interval simulation with different kind of artefacts. Can also return peak vector.
c. The correction sub-module has been largely rewritten and now include systole.correction.correct_extra, systole.correction.correct_missed, systole.correction.interpolate_bads, systole.correction.correct_rr, systole.correction.correct_peaks, systole.correction.correct_missed_peaks, systole.correction.correct_extra_peaks. These function can correct artefacts either using peaks addition/removal or by interpolation of the RR time series.

Enhancements

a. The detection sub-module has been improved. It is now about 10x faster and returns more information. The main function has been renamed to systole.detection.rr_artefacts.

Bugfixes

a. systole.correction.interpolate_clipping: add exception in case of clipping artefacts at the edge of the signal segment. This can cause cash during recording. The default behavior is now to decrement the last/first item in case of threshold value. The threshold can be changed manually. This procedure can result in slightly inaccurate interpolation, using a longer recording should always be preferred when possible.
b. The PPG signal simulator used for testing can now run infinitely.
