pymovements.datasets.base.PublicDataset.pix2deg

PublicDataset.pix2deg(verbose: bool = True) → None

Compute gaze positions in degrees of visual angle from pixel coordinates.

This requires an experiment definition and also assumes that the columns ‘x_left_pix’,

‘y_left_pix’, ‘x_right_pix’ and ‘y_right_pix’ are available in the gaze dataframe.

After success, the gaze dataframe is extended by the columns ‘x_left_dva’, ‘y_left_dva’, ‘x_right_dva’ and, ‘y_right_dva’.

Parameters

verbose (bool) – If True, show progress of computation.

Raises

AttributeError – If gaze is None or there are no gaze dataframes present in the gaze attribute, or if experiment is None.
