This directory contains compressed multiple alignments of 241 mammalian
species and measurements of evolutionary conservation from the Zoonomia Project

This track shows multiple alignments of 241 vertebrate species and measurements of evolutionary conservation from the Zoonomia Project.

              https://zoonomiaproject.org/the-project/

The multiple alignments were generated using the Cactus comparative genomics
alignment system. Cactus produces reference-free, whole-genome multiple
alignments.

       https://github.com/ComparativeGenomicsToolkit/cactus/

The base-wise conservation scores are computed using phyloP from the PHAST
package, for all species.  This version was prepared by
Michael Dong (Uppsala U) with an improved neutral model incorporating better
versions of ancestral repeats. 

Please note the table of species in the description page for the track:

hg38.cactus241way.scientificNames.nh - phylogenetic tree used during the
                                     - cactus multiple alignment

hg38.cactus241way.nh - some of the species translate to UCSC database
                     - equivalents.  Tree used for display in the genome
                     - browser, identical to the scientificNames tree.

hg38.cactus241way.phyloP.wigFix.gz - PhyloP scores in fixed step wiggle format

md5sum.txt - md5sum checksums for the files in this directory

For a description of the fixed step wiggle data file format, see:

The maf/chr*.maf.gz files each contain all the alignments to that particular
human chromosome.  Beware, the compressed data size of these files
is about 1.2 Tb, uncompressed size is about 9.1 Tb.
