After reading the tutorial from https://perun.biochem.dal.ca/user-wiki/doku.php?id=phylogeny_protocol5, users should be able to set up the PhyloToL running environment. However, there is a need for users to have a basic knowledge of bioinformatics in order to take full advantage of PhyloToL (https://github.com/Katzlab/PhyloTOL)in particular, the ability to use the basic OrthoMCLDB and dash shell in a Linux/Unix environment.

the pipeline in a clear, concise and easy-to-follow manner

 We have also guided users with a sample data set and results for each step, which can help users reproduce the results and figures with their own data.

8.  Explore genome evolution of diverse eukaryotes-PhyloToL (Phylogenetic Tree of Life)
PhyloToL is a phylogenomic pipeline aimed at exploring evolutionary hypotheses at ancient (i.e. >100 million year) time scales. PhyloToL was originally designed for analyses of the eukaryotic tree of life, the flexibility of PhyloToL allows users to add their taxa of interest and to explore hypotheses at varying taxonomic levels.

PhyloToL consists of four major components: 
* Gene family (GF) assessment per taxon (i.e. adding taxa to the database); 
* Refinement of homologs and gene tree reconstruction, 
* Tree-based contamination removal; 
* Building of a supermatrix for species tree reconstruction. 
These components can be executed independently. PhyloToL is written primarily in the Python 3 programming language but it also incorporates Perl, Ruby and Bash custom scripts. PhyloToL only runs through the command line (i.e. there is no a GUI), therefore a minimum knowledge of UNIX is required. PhyloToL was designed to run on a cluster, but can also easily be run on desktop computers with single or multiple threads.
