Phylogenetic Analysis with Space/Time models (PHAST) is a freely available software package consisting of a collection of command-line programs and supporting libraries for comparative and evolutionary genomics. Best known as the search engine behind the Conservation tracks in the University of California, Santa Cruz (UCSC) Genome Browser, PHAST also includes several tools for phylogenetic modeling, functional element identification, as well as utilities for manipulating alignments, trees and genomic annotations.
The PHAST project was initiated by Principal Investigator, Adam Siepel with extensions by Melissa Hubisz.
The phastWeb application was developed by Ritika Ramani.
phastCons: Conservation scoring and identification of conserved elements
phyloFit: Fitting of phylogenetic models to aligned DNA sequences
phyloP: Computation of p-values for conservation or acceleration, either lineage-specific or across all branches
phastOdds: Log-odds scoring for phylogenetic models or phylo-HMMs
exoniphy: Phylogenetic exon prediction
dless: Prediction of elements under lineage-specific selection
prequel: Probabilistic reconstruction of ancestral sequences
phastBias: Identification of GC-biased gene conversion using a phylo-HMM
