mne.channel_indices_by_type

mne.channel_indices_by_type(info, picks=None)

Get indices of channels by type.

Parameters

infoinstance of Info

A measurement info object.

picksstr | list | 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.

Returns

idx_by_typedict

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