biopsykit.signals.eeg package¶
Module for EEG data analysis and visualization.
- class biopsykit.signals.eeg.EegProcessor(data, sampling_rate=None, time_intervals=None, include_start=False)[source]¶
Bases:
biopsykit.signals._base._BaseProcessor
Initialize an
EegProcessor
instance.You can either pass a data dictionary ‘data_dict’ containing EEG data or dataframe containing EEG data. For the latter, you can additionally supply time information via
time_intervals
parameter to automatically split the data into single phases.- Parameters
data (
DataFrame
or dict) – dataframe (or dict of such) with EEG datasampling_rate (float, optional) – sampling rate of recorded data
time_intervals (dict or
Series
, optional) – time intervals indicating howdata
should be split. Can either be aSeries
with the start times of the single phases (the phase names are then derived from the index) or a dictionary with tuples indicating start and end times of phases (the phase names are then derived from the dict keys). Default:None
(data is not split further)include_start (bool, optional) –
True
to include the data from the beginning of the recording to the first time interval as the first phase (then namedStart
),False
otherwise. Default:False
- eeg_result: Dict[str, pandas.core.frame.DataFrame]¶
Dictionary with EEG processing result dataframes, split into different phases.
- relative_band_energy(freq_bands=None, title=None)[source]¶
Process EEG signal.
- Parameters
freq_bands (dict) –
dictionary with frequency bounds of EEG frequency bands. By default (
None
) the following frequency band definition (in Hz) is used:theta
: [4, 8]alpha
: [8, 13]beta
: [13, 30]gamma
: [30, 44]
title (str, optional) – title of ECG processing progress bar in Jupyter Notebooks or
None
to leave empty. Default:None
- Return type
None
