mne.create_info#

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

Create a basic Info instance suitable for use with create_raw.

Parameters:

ch_nameslist of str | int: Channel names. If an int, a list of channel names will be created from range(ch_names).
sfreqfloat: 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’, ‘dbs’, ‘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 | None: Control verbosity of the logging output. If None, use the default verbosity level. See the logging documentation and mne.verbose() for details. Should only be passed as a keyword argument.

Returns:

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

Notes

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:
