bycycle.utils.epoch_df

bycycle.utils.epoch_df(df_features, sig_len, epoch_len)

Reshape a dataframe into a list of dataframes.

Parameters:

df_featurespandas.DataFrame

A dataframe containing shape and burst features for each cycle.

sig_lenint

Length of a 1D time series.

epoch_lenint

The length of each epoched data in units of signal samples.

Returns:

dfs_featureslist of pd.DataFrame

A list of features dataframes that have been epoched.

Examples

Epoch a dataframe in 1 seconds intervals:

>>> from neurodsp.sim import sim_bursty_oscillation
>>> from bycycle.features import compute_features
>>> fs = 500
>>> sig = sim_bursty_oscillation(10, fs, freq=10)
>>> df_features = compute_features(sig, fs, f_range=(8, 12), center_extrema='peak')
>>> dfs_features = epoch_df(df_features, len(sig), fs)
