Microscopy time-lapses and simulation data needed to reproduce the results from the manuscript “Falsifying computational models of endothelial cell network formation through quantitative comparison with in vitro models”by T.M. Vergroesen, V. Vermeulen and R.M.H. Merks "Figure 1": This folder contains phase contrast time-lapses of endothelial network formation in subfolder "Data" and the image analysis output in subfolder "Output" which can be used to generate results of figure 1 of the paper "Figure 2": This folder contains all simulation data in subfolder "Data" and the image analysis output in subfolder "Output" which can be used to generate results of figure 2 of the paper "Figure 3": This folder contains phase contrast time-lapsesin subfolder "Data" and the image analysis output in subfolder "Output" which can be used to generate results of figure 3 of the paper "Figure 4": This folder contains all simulation data in subfolder "Data" and the image analysis output in subfolder "Output" which can be used to generate results of figure 4 of the paper
