ctrappy.stepfinder

Run step finding on a bleaching trace.

ctrappy.stepfinder.find_steps(x, y, min_step_size, min_plateau_length=1)

Find steps in a signal using change-point analysis.

Parameters:

• x (numpy array of floats) – x values

• y (numpy array of floats) – y values (signal).

• min_step_size (float) – Minimum step size.

• min_plateau_length (int) – Minimum length of plateaus. Default: 1.

Returns:

• step_locs (numpy array of ints) – Location indices of steps.

• step_sizes (numpy array of floats) – Sizes of steps.

• sig_det (numpy array of floats) – Detected signal, only containing steps.
