Epoching a Stream in real-time
==============================

.. include:: ./../../links.inc

The :class:`~mne_lsl.stream.EpochsStream` object can be used similarly to
:class:`mne.Epochs` to create epochs from a continuous stream of samples around events
of interest.

.. note::

    The :class:`~mne_lsl.stream.EpochsStream` object is designed to work with
    any ``Stream`` object. At the time of writing, only
    :class:`~mne_lsl.stream.StreamLSL` is available, but any object inheriting from the
    abstract :class:`~mne_lsl.stream.BaseStream` object should work.

A :class:`~mne_lsl.stream.EpochsStream` object support peak-to-peak rejection, baseline
correction and detrending.

Event source
------------

A :class:`~mne_lsl.stream.EpochsStream` object requires an event source to create
epochs. 3 event sources are supported:

- a set of ``'stim'`` channels within the attached ``Stream`` object.
- a set of ``'stim'`` channels within a separate ``Stream`` object.
- an irregularly sampled ``Stream`` object.

.. note::

    In the case of an irregularly sampled ``Stream`` object, only numerical streams are
    supported at the moment because interaction with ``str`` streams in Python is not
    as performant as interaction with numerical streams.

Set of ``'stim'`` channels
--------------------------

The set of ``'stim'`` channels from which the events are extracted can be either part
of the regularly sampled ``Stream`` object epoched (argument ``stream``) or part of a
separate regularly sampled ``Stream`` object (argument ``event_stream``). In both case,
the channel(s) type should be ``'stim'`` and the channel(s) should be formatted for
:func:`mne.find_events` to correctly extract the events. The channels to consider are
provided in the argument ``event_channels`` and the events to consider in the argument
``event_id``. Let's create epochs around the event ID ``2`` from the ``'STI 014'``
channel of MNE's sample dataset.

.. note::

    A ``chunk_size`` of 200 samples is used here to ensure stability and reliability
    while building the documentation on the CI. In practice, a ``chunk_size`` of 200
    samples is too large to represent a real-time application.

In the cell above, a mock LSL stream is created using the ``'meg'`` and ``'stim'``
channels of MNE's sample dataset. Now, we need to create a
:class:`~mne_lsl.stream.StreamLSL` object connected to this mock LSL stream. The
channel ``"MEG 2443"`` is marked as bad and the signal is filtered with a low-pass
filter.

Now, we can create epochs using this stream as source for both the epochs and the
events. The ``'stim'`` channel ``'STI 014'`` is used to extract the events and epochs
are created around the event ID ``2`` using the gradiometer channels. The epochs are
created around the event, from 200 ms before the event to 500 ms after the event. A
baseline correction is applied using the 200 first ms of the epoch as baseline.

Note the ``bufsize`` argument in the cell above. This argument controls the number of
epochs that are kept in memory. The actual size of the underlying numpy array depends
on the number of epochs, the number of samples (controlled by ``tmin`` and ``tmax``)
and the number of channels.

Let's wait for a couple of epochs to enter in the buffer, and then let's convert the
array to an MNE-Python :class:`~mne.Epochs` object and plot the evoked response.

Irregularly sampled stream
--------------------------

The event source can also be an irregularly sampled stream. In this case, each channel
represents a separate event. A new value entering the buffer of a channel is
interpreted as an event, regardless of the value itself. For instance, we can fake
an irregularly sampled numerical stream using a :class:`~mne_lsl.player.PlayerLSL`
with a :class:`~mne.io.Raw` object which has :class:`~mne.Annotations` attached to it.

Let's first inspect the event stream once a couple of samples have been acquired.

.. GENERATED FROM PYTHON SOURCE LINES 191-198

    while stream_events.n_new_samples < 3:
        time.sleep(0.5)
    data, ts = stream_events.get_data(winsize=stream_events.n_new_samples)
    print("Array of shape (n_channels, n_samples): ", data.shape)
    data





.. rst-class:: sphx-glr-script-out

 .. code-block:: none

    Array of shape (n_channels, n_samples):  (2, 3)

    array([[0.1, 0. , 0.1],
           [0. , 0.1, 0. ]])



.. GENERATED FROM PYTHON SOURCE LINES 199-215

Each channel corresponds to a given annotation, ``0`` to ``'ignore'`` and ``1`` to
``'event'``. The value is ``0`` when no annotation is present, and ``x`` when an
annotation is present, with ``x`` being the duration of the annotation.

Thus, this array can be interpreted as follows:

.. code-block:: python

     array([[0.1, 0. , 0.1],
           [0. , 0.1, 0. ]])

- An annotation of 0.1 seconds labelled ``'ignore'`` was received at ``ts[0]``.
- An annotation of 0.1 seconds labelled ``'event'`` was received at ``ts[1]``.
- An annotation of 0.1 seconds labelled ``'ignore'`` was received at ``ts[2]``.

We can now use those 2 streams to create epochs around the events of interest.

Let's wait for a couple of epochs to enter in the buffer, and then let's convert the
array to an MNE-Python :class:`~mne.Epochs` object and plot the time-frequency
representation of the evoked response.

Finally, in this case a single event was kept in the
:class:`~mne_lsl.stream.EpochsStream`, but if more events are retained, it is
important to know which one is which. This information is stored in the property
:attr:`~mne_lsl.stream.EpochsStream.events` of the
:class:`~mne_lsl.stream.EpochsStream`, which is an internal buffer of the event codes.

When you are done with a :class:`~mne_lsl.player.PlayerLSL`, a
:class:`~mne_lsl.stream.StreamLSL` or a :class:`~mne_lsl.stream.EpochsStream` don't
forget to free the resources they use to continuously mock an LSL stream or
