DynTrack

Python package for the study of particle dynamics from 2D tracks

Installation

pip install -U dyntrack

Usage

import dyntrack as dt

DT = dt.ut.load_data("tracks.csv","Position X","Position Y","Parent","Time","background.tiff")

dt.tl.vector_field(DT)
dt.pl.vector_field(DT)

dt.tl.FTLE(DT, 20000,5)
dt.pl.FTLE(DT)

dt.tl.fit_ppt(DT,seed=1)
dt.pl.fit_ppt(DT)
