From: TINNiK: inference of the tree of blobs of a species network under the coalescent model
Four TINNiK trees of blobs for a simulated sample of \(n = 1000\) gene trees on network \({\mathcal {N}}^+\) of Fig. 1 (L) with \(k=1\) (moderate ILS), for \(\beta = 1\) and \(\alpha =0.02, 0.01, 10^{-7}, 10^{-23}\). Increasing resolution as \(\alpha \) is decreased is typical. The true tree of blobs (bottom, left) is inferred for a large range of test levels \(\alpha \in [10^{-7},\, 0.001]\). Although the (bottom, right) tree is over-resolved when \(\alpha = 10^{-23}\), each split is compatible with a tree displayed on \({\mathcal {N}}^+\)
