meeg_utils.qc.Blinks

class meeg_utils.qc.Blinks(*, min_rate=None)

Blink rate from the EOG channel(s), a test that the EOG works.

Blinks are detected with mne.preprocessing.find_eog_events() (MNE defaults). Spontaneous blink rates of healthy adults are around 17 per minute at rest and fall to about 4.5 per minute while reading (Bentivoglio et al., 1997, Mov Disord 12:1028); a much lower rate usually means a detached or misplaced EOG electrode. A flat EOG channel is always flagged.

Parameters:

min_rate (float | None) – Blinks per minute below which the EOG is flagged. Blink rates vary widely between people and tasks (Bentivoglio et al., 1997), so the default None reports the rate without a verdict.

__init__(*, min_rate=None)

Methods

__init__(*[, min_rate])
compute(raw)	Measure the recording.
get_metadata_routing()	Get metadata routing of this object.
get_params([deep])	Get parameters for this estimator.
not_applicable(raw)	Return why the check cannot run on raw, or None if it can.
plot([kind, inst])	Draw quality-control figures.
set_params(**params)	Set the parameters of this estimator.

Attributes

level	The worst verdict of the findings ("ok" if there are none).
modalities	Data types the check needs at least one of ("meg", "eeg").
name	Key of the check in reports.
plot_kinds	kind -> whether it needs data (inst).
systems	Acquisition systems the check applies to; None means all.

name: ClassVar[str] = 'blinks'

Key of the check in reports.

plot_kinds: ClassVar[dict[str, bool]] = {'blinks': False}

kind -> whether it needs data (inst). Each kind is drawn by a _plot_<kind>(inst, **kwargs) method.

Type:

Figures the object can draw once fitted

not_applicable(raw)

Return why the check cannot run on raw, or None if it can.

Parameters:

raw (Raw) – The recording.

Returns:

The reason, or None.

Return type:

str | None
