Naser-khdour model violation in phylogenetics
Witryna9 gru 2024 · More generally, deviations from the standard model assumptions are observed to increase with evolutionary distance between the taxa. The appreciation of the impact of these violations of the model assumptions on phylogeny estimation has increased in recent years [57, 59,60,61,62]. For example, Naser-Khdour et al. noted: Witryna3 maj 2024 · Sequence simulation process with two scenarios: ( A) Simulating an MSA from a phylogenetic tree and a Markov substitution model, and ( B) Simulating an MSA that mimics the underlying evolutionary process of a user-provided MSA.

Witryna8 wrz 2024 · IQ-TREE provides three matched-pairs tests of symmetry (Naser-Khdour et al., 2024) to test the two assumptions of stationarity and homogeneity. A simple analysis: iqtree2 -s example.phy -p example.nex --symtest-only Just to be clear this tests whether the rate between two partitions (genes) is homogeneous. Witryna17 gru 2024 · Sequence simulators play an important role in phylogenetics.
