philistine.mne.abs_threshold

philistine.mne.abs_threshold(epochs, threshold, eeg=True, eog=False, misc=False, stim=False)[source]

Compute mask for dropping epochs based on absolute voltage threshold.

Parameters:
  • epochs (instance of Epochs) – The epoched data to do threshold rejection on.
  • threshold (float) – The absolute threshold (in volts) to reject at.
  • eeg (bool) – If True include EEG channels in thresholding procedure.
  • eog (bool) – If True include EOG channels in thresholding procedure.
  • misc (bool) – If True include miscellaneous channels in thresholding procedure.
  • stim (bool) – If True include stimulus channels in thresholding procedure.
Returns:

rej – Boolean mask for whether or not the epochs exceeded the rejection threshold at any time point for any channel.
Return type:

instance of ndarray

Notes

More precise selection of channels can be performed by passing a ‘reduced’ Epochs instance from the various picks methods.
