pymovements.gaze.GazeDataFrame.pos2acc#

GazeDataFrame.pos2acc(window_length: int = 7, degree: int = 2, mode: str = 'interp', cval: float = 0.0) → None[source]#

Compute gaze acceleration in dva/s^2 from dva position coordinates.

This method requires a properly initialized experiment attribute.

After success, the gaze dataframe is extended by the resulting velocity columns.

Parameters:

  • window_length – The window size to use.

  • degree – The degree of the polynomial to use.

  • mode – The padding mode to use.

  • cval – A constant value for padding.

Raises:

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