Epochs, artifact rejection and combining runs
=============================================

Preprocessing works on each run separately. Epoching is a second stage,
applied to each preprocessed run; the epochs of a session's runs are then
combined. This tutorial cuts MNE's ``sample`` EEG into epochs around the
auditory and visual stimuli, repairs or rejects the bad ones with
autoreject, and combines two runs.

The sample recording is a single run. To show how runs are combined, we
treat its two halves as two runs, each preprocessed on its own (here only
a high-pass filter and an average reference, to keep the tutorial fast; in
practice the ``eeg-erp`` preset).

The epochs stage
----------------
The ``eeg-erp`` epochs stage low-passes the data at 40 Hz, cuts epochs from
-0.2 to 0.5 s with a pre-stimulus baseline, and runs local autoreject (all
MNE-BIDS-Pipeline defaults). Only the events need to be given:

autoreject
----------
Local autoreject (Jas et al., 2017) learns a peak-to-peak threshold per
channel. Within an epoch it interpolates the few channels above their
threshold; epochs with too many bad channels are dropped. Each row is a
channel and each column an epoch:

Combine the runs
----------------
:func:`meeg_utils.epochs.combine` concatenates the runs after checking
that they agree: the same event codes, the same channels (a channel bad in
one run is marked bad in all, ``bads="union"``), and for MEG a head
position within 2 mm (otherwise map the runs to a common head position
first with :class:`~meeg_utils.steps.HeadAlign`).

        - variables starting with `--jp-` are Jupyter styles, *some of which* are also
          available in VSCode. Here we try the `--theme-` variable first, then fall back to
