mne.channel_indices_by_type#

mne.channel_indices_by_type(info, picks=None, *, exclude=())[source]#

Get indices of channels by type.

Parameters:
infomne.Info

The mne.Info object with information about the sensors and methods of measurement.

picksstr | array_like | slice | None

Channels to include. Slices and lists of integers will be interpreted as channel indices. In lists, channel type strings (e.g., ['meg', 'eeg']) will pick channels of those types, channel name strings (e.g., ['MEG0111', 'MEG2623'] will pick the given channels. Can also be the string values 'all' to pick all channels, or 'data' to pick data channels. None (default) will pick all channels. Note that channels in info['bads'] will be included if their names or indices are explicitly provided.

excludelist | str

Set of channels to exclude, only used when picking based on types (e.g., exclude=”bads” when picks=”meg”).

New in v1.10.0.

Returns:
idx_by_typedict

A dictionary that maps each channel type to a (possibly empty) list of channel indices.
