The dataset is in compressed NumPy format and can be found in notebooks/data_ECG_8hrs_200Hz.npz. This is a flexible function that can be used to detect NREM/REM periods.Īdded the yasa.hrv_stage() function, which calculates heart rate (HR) and heart rate variability (HRV) by stage and periods.Īdded a new dataset containing 8 hours of ECG data. PR 108Īdded the yasa.hypno_find_periods() function to find sequences of consecutive values in hypnogram that are longer than a certain duration. ot_hypnogram() now draws the hypnogram with () instead of (). Now select figure aesthetics (e.g., size, dpi) by opening a instance and passing to ax. Transition probabilities can be user-defined or will default to those published in Metzner et al., 2021, Commun Biol (see Figure 5b).Īdded the ax keyword-argument to ot_hypnogram() and removed figsize. The hypnogram is simulated as a Markov sequence based on sleep stage transition probabilities. PR 115Īdded the yasa.simulate_hypno() function to generate a simulated hypnogram, primarily for testing purposes and tutorials. Solved a bug in the spindles detection which resulted in no spindle being detected on some systems. Big shoutout to for his huge help on this new version!
