PhyKIT: a broadly applicable UNIX shell toolkit for processing and analyzing phylogenomic data.

Area of Science:

• Bioinformatics
• Computational Biology
• Evolutionary Biology

Background:

• Diverse biological disciplines analyze multiple sequence alignments (MSAs) and phylogenetic trees for information content, evolutionary inference, and gene function prediction.
• Automated processing of MSAs and trees is challenging due to the lack of a unified toolkit.
• PhyKIT addresses this gap by providing a comprehensive set of tools for MSAs and trees.

Purpose of the Study:

• Introduce PhyKIT, a novel toolkit for processing MSAs and phylogenetic trees.
• Provide a unified solution for common tasks in phylogenomic data analysis.
• Facilitate the examination and biological interpretation of large phylogenomic datasets.

Main Methods:

• PhyKIT is a command-line toolkit for the UNIX shell environment.
• It includes 30 functions for processing MSAs and trees.
• Key functions include mutation rate estimation, bias evaluation, molecular clock violation assessment, and bipartition collapsing.

Main Results:

• PhyKIT demonstrates utility in summarizing MSA and tree information content to diagnose data biases.
• It aids in evaluating gene-gene covariation of evolutionary rates to identify functional relationships.
• PhyKIT helps identify lack of resolution events (polytomies) suggestive of rapid radiation or data limitations.

Conclusions:

• PhyKIT is a valuable resource for researchers working with MSAs and phylogenetic trees.
• The toolkit simplifies and enhances the analysis of complex evolutionary data.
• It is expected to be widely adopted for processing and deriving biological meaning from large phylogenomic datasets.
