fitgrid.epochs module¶

class fitgrid.epochs.Epochs(epochs_table, time, epoch_id, channels)[source]¶

Bases: object

Container class used for storing epochs tables and exposing statsmodels.

Parameters

epochs_table (pandas DataFrame) – long form dataframe containing epochs with equal indices
time (str) – time column name
epoch_id (str) – epoch identifier column name
channels (list of str) – list of channel names to serve as dependent variables

Returns

epochs – epochs object

Return type

Epochs

distances()[source]¶

Return scaled Euclidean distances of epochs from the “mean” epoch.

Notes

Distances are scaled by dividing by the max.

plot_averages(channels=None, negative_up=True)[source]¶

Plot grand mean averages for each channel, negative up by default.

Parameters

channels (list of str, optional, defaults to all channels) – list of channel names to plot the averages
negative_up (bool, optional, default True) – by convention, ERPs are plotted negative voltage up

Returns
