Top part: A, B and $\frac{B}{A}$ values obtained for each model (infinite cylinder model and 3D-cell simulations) when fitting the function A ​+ ​B ​× ​cos (2ϕ). These values can be compared to the grey column on the left-hand side that indicates the average A, B and $\frac{B}{A}$ calculated over five metabolites (mean ​± ​s.d.). Error on parameters extracted from geometric models (D_free, d_fiber) was estimated using Monte Carlo simulations. Models exhibiting embranchments exhibit lower $\frac{B}{A}$ values that better match our experimental data. Bottom part: Fitting to the infinite cylinders model for each 3D-cell simulation. This model fails to yield the expected ground truth values for D_free and d_fiber (i.e. 0.35 ​μm²/ms and 1 ​μm) for all simulations. Most strikingly, the obtained values are close to that of the average D_free and d_fiber obtained for our experimental data (mean ​± ​s.d. over five metabolites), further illustrating the fact that the infinite cylinders model does not satisfactorily describe the experimental data.
