EpochExtractor turns a continuous raw recording into a set of fixed-length trials (epochs) locked to stimulus or response events. Each epoch can optionally have baseline correction applied and can be rejected if any channel exceeds a peak-to-peak amplitude threshold.

The output epochs are stored as MNEEpochData objects (data matrix + event code + tmin/tmax

• rejection flag) which integrate with the rest of the MNE-CPP analysis pipeline.
