v0.2.0 (October 2021)

Highlights

This is a major release that introduces a new plotting backend using Bokeh instead of Plotly, several API changes and performance improvement (Numba).

The plots submodule now includes the following functions:

  • :func:systole.plots.plot_circular
  • :func:systole.plots.plot_ectopic
  • :func:systole.plots.plot_events
  • :func:systole.plots.plot_evoked
  • :func:systole.plots.plot_frequency
  • :func:systole.plots.plot_pointcare
  • :func:systole.plots.plot_raw
  • :func:systole.plots.plot_rr
  • :func:systole.plots.plot_shortlong
  • :func:systole.plots.plot_subspaces

These functions can be called using Bokeh or Matplotlib as backend (plot_circular only accepts Matplotlib for now).

All the methods available in :func:systole.detection.ecg_peaks are now accelerated with Numba.

  • |Enhancement| Add Numba support for :func:systole.detector.pan_tompkins() (~7x faster)
  • |Enhancement| Add Numba support for :func:systole.detector.hamilton() (~10x faster)
  • |Enhancement| Add Numba support for :func:systole.detector.christov() (~30x faster)
  • |Enhancement| Add Numba support for :func:systole.detector.engelse_zeelenberg() (~20x faster)

This also drops py-ecg-detectors dependency, and the refactored code is now included in Systole.

This release also includes some API changes and renaming for consistency (oxi_peaks -> ppg_peaks).

Changes

  • |Api| Remove support for Plotly. Add support for Bokeh. Merge interactive and non-interactive modules into a unique :func:plots module.

  • |Docs| Use PyData Sphinx theme.

  • |Docs| Several additions to the tutorials pages, now divided into 5 Chapters:

  1. Physiological signal analysis
  2. Detecting cycles
  3. Detecting and correcting artefacts
  4. Heart rate variability
  5. Instantaneous heart rate and evoked heart rate

  • |Docs| Add examples for :func:systole.correction.correct_peaks() and :func:systole.correction.correct_rr() in the gallery.

  • |Enhancement| |Feature| |API| Most of the functions now accept inputs as peaks (boolean vector), peaks_idx (int indexes vector), rr_ms (floats RR intervals in miliseconds) or rr_s (floats RR intervals in seconds). :func:systole.utils.to_rr() has been renamed to :py:func:systole.utils.input_conversion() and support the conversion between data types.

  • |Fix| |Enhancement| :func:systole.detection.ppg_peaks() now handles negative values/ low sampling rate.

  • |Enhancement| :func:systole.correction.correct_peaks() and :func:systole.correction.correct_rr() have been improved for performances, allows n iterations and print results.

  • |Enhancement| utils.to_epochs() now accept multiple condition (as list) and returns rejection vectors for each one. The code has also been simplified and runs faster.

  • |Fix| Remove use of outdated.
