dyntrack.tl.fit_ppt

dyntrack.tl.fit_ppt(DT, times=None, lam=10, sigma=10, copy=False, **kwargs)

Compute a principal tree from partical position at each frame.

Parameters

• DT (DynTrack) – A dyntrack.DynTrack object.

• times (Optional[Sequence]) – set of timepoints/frames to use for the fitting, by default uses all.

• lam (float) – Lambda parameter from SimplePPT algorithm.

• sigma (float) – Sigma parameter from SimplePPT algorithm.

• copy (bool) – Return a copy instead of writing to DT.

• **kwargs – Additional parameters to be passed to simpleppt.ppt()

Returns

DT – if copy=True it returns or else add fields to DT:

.ppts

List of principal trees calculated per frame.

Return type

dyntrack.DynTrack
