{% endif %}Root-to-tip regression can be used to visually assess the temporal signal in the phylogenetic tree. It plots the genetic distance from the root against the sampling dates of the sequences.
Primer: the slope is the estimated evolutionary rate (substitutions/site/year, using decimal-year dates), the x-intercept estimates tMRCA, R² is the fraction of variation explained by the regression, and r is the Pearson correlation coefficient. These values are sensitive to tree rooting, so an incorrect root placement can shift the inferred rate, tMRCA, and fit statistics.

Convergent mutations are mutations that have independently arisen multiple times across the tree.
Large numbers of convergent SNPs can indicate convergent evolution (real) OR alignment/reconstruction errors (artifacts).

Ancestral state reconstruction files must be supplied to check for convergent mutations.
No convergent mutations flagged.
{% endif %}Reversions are mutations that revert to a previous state observed in the tree.
If assembly references are supplied, reversions can flag potential assembly errors.
