BASE - pronunced /'baze/ - is a workflow built to ease the inference and interpretation of selection regimes in the context of comparative genomics. While the majority of these analyses are restricted to ubiquitous genes - i.e. genes which are present in all the species considered - BASE allows to integrate non-ubiquitous genes - i.e. genes which are not present in all the species considered - in a straightforward and reproducible manner. Nonetheless, BASE presents many other features, including replicates, gene-trees and species-trees analyses.

BASE has been designed to function in two indipendent steps:

1. analyze infer & compare a general and alternative models for each gene.

2. extract retrive metrics of branches and/or clades, allowing a treshold for missing species.

More information on each mode can be accessed by typing --analize or --extract followed by -h.

BASE leverages several other pieces of software, most notably codeml. Here is the workflow schematic:

You can find informations on installation and usage following the relative tutorials.

A preprint for BASE is available here.
