<p>Turning to the right panel of Figure 2, we see that <code>$rms_cca_distance</code> attains the local minimum at <i>p</i>=2. Therefore, we can deduce that the best-fit tree trajectory for the myoblast data consists of <i>p</i>+1=3 principal paths. <code>$n_principal_paths_candidates[1]</code> also tells us the number pr
