mne.preprocessing.read_fine_calibration

mne.preprocessing.read_fine_calibration(fname)[source]

Read fine calibration information from a .dat file.

The fine calibration typically includes improved sensor locations, calibration coefficients, and gradiometer imbalance information.

Parameters
fnamestr

The filename.

Returns
calibrationdict

Fine calibration information. Key-value pairs are:

  • ch_names

    List of str of the channel names.

  • locs

    Coil location and orientation parameters.

  • imb_cals

    For magnetometers, the calibration coefficients. For gradiometers, one or three imbalance parameters.
