hare-phylogenomics

Pipeline used for analyses of whole-exome data from 15 hare species and 2 outgroup rabbit species. We performed species tree inference, and estimated hybridization with species network inference and summary statistics (D-statistics, fraction of admixture, admixture proportion and f-branch statistics).

In each section bellow, I describe the pipeline used in a markdown file (follow links below). Scripts referenced in each section can be found inside the respective folders.

python scrips use python2.7.

Sections

1. Read processing, pseudoreferences and mapping
2. Calling genotypes and creating a consensus fasta
3. Species tree and ML whole exome tree
4. Divergence time inference (MCMCtree)
5. Discordance analyses between gene trees and species tree
6. Network analyses (PhyloNet and TreeMix)
7. Estimating divergence and diversity per species
8. Admixture analyses (D_min, f-branch, f_d, f_hom)
