Sentence examples for required branch length from inspiring English sources

GenNon-h produces directly transition matrices of the required branch length (for any of the Markov models described above) and therefore does not assume time-homogeneity (not globally over the tree, nor locally at the edges).

The simulation process required branch lengths that are roughly proportional to time, which means using an ultrametric tree in our case because all the tribes exist in the present day.

To enforce this option in AnGST, the species tree required branch lengths scaled in units of time.

We decided to use TFSI as an alternative to the parsimony models because it does not assume a model of evolutionary change or require branch lengths.

All likelihood models require branch lengths to estimate the probability of a transition along a given branch, and any rates used in such models are proportional to the units of branch length.

Correct phylogenetic inference using likelihood-based methods requires accurate branch length estimates.

However, GMYC analysis is currently computationally more difficult to implement, especially because it requires a detour via branch length optimization and computation of an ultrametric tree and algorithms, which are prone to error if branch lengths are zero.

Because stochastic mapping requires model parameters and branch length estimation, stochastic mapping performance varies in each simulation depending on the accuracy of these parameters.

To infer the ancestral GI values for these species, we required both phylogenetic topology and branch length information for the extant species because their membership in the nested hierarchy of a phylogeny implies that they are not statistically independent.

In general, nodes that were filled with closely related isolates required only approximately 100 positions for accurate placement, while nodes containing isolates with long branch lengths required far more positions to be called for accurate placement.

The implementation of the directional model requires variation in root-to-tip branch length [ 3, 55, 65] which in our otherwise ultrametric tree is provided by the inclusion of fossil data.
