# Scripts generating these files

(1) Creating syntenic block .bed files

(2) Assigning most recent common ancestor (MRCA) and patristic distances to syntenic blocks

### Bed file

# File columns

["chr", "start", "end", "strand",  "reference_genome", "species_count", "length_synteny_block", "max_mrca",  "max_patr"]

# Definitions

"max_mrca" = the phylogenetic distance from Homo sapiens to the most recent common ancestor of the oldest taxon. 

"max_patr" = the phylogenetic distance from Homo sapiens to the oldest taxon.

"species_count" = the number of species' genomes the syntenic block maps to.
