mne.create_info(ch_names, sfreq, ch_types='misc', verbose=None)[source]

Create a basic Info instance suitable for use with create_raw.

ch_nameslist of str | int

Channel names. If an int, a list of channel names will be created from range(ch_names).


Sample rate of the data.

ch_typeslist of str | str

Channel types, default is 'misc' which is not a data channel. Currently supported fields are ‘ecg’, ‘bio’, ‘stim’, ‘eog’, ‘misc’, ‘seeg’, ‘ecog’, ‘mag’, ‘eeg’, ‘ref_meg’, ‘grad’, ‘emg’, ‘hbr’ or ‘hbo’. If str, then all channels are assumed to be of the same type.

verbosebool, str, int, or None

If not None, override default verbose level (see mne.verbose() and Logging documentation for more). If used, it should be passed as a keyword-argument only.

infoinstance of Info

The measurement info.


The info dictionary will be sparsely populated to enable functionality within the rest of the package. Advanced functionality such as source localization can only be obtained through substantial, proper modifications of the info structure (not recommended).

Note that the MEG device-to-head transform info['dev_head_t'] will be initialized to the identity transform.

Proper units of measure: * V: eeg, eog, seeg, emg, ecg, bio, ecog * T: mag * T/m: grad * M: hbo, hbr * Am: dipole * AU: misc
