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.
