PEWO

PEWO benchmarks and evaluates phylogenetic placement (PP) tools to compare accuracy, computational cost, parameter effects, and genetic marker suitability for species identification.

Key Features:

• Benchmarking Capability: Provides workflows to assess and compare different phylogenetic placement tools using performance metrics such as accuracy under varying conditions.
• Parameter Optimization: Enables fine-tuning of parameters for individual PP software to determine parameter settings that improve placement performance on specific datasets.
• Genetic Marker Selection: Assists in identifying suitable genetic markers for species identification tasks based on phylogenetic placement outcomes.
• Computational Cost Analysis: Evaluates computational resources required by PP tools to quantify efficiency alongside accuracy.

Scientific Applications:

• Taxonomic identification: Supports accurate species identification through evaluation of phylogenetic placement methods and marker choice.
• Evolutionary biology: Informs selection of PP tools and parameters for studies of evolutionary relationships using reference trees.
• Biodiversity assessment: Enables comparison of placement approaches to improve detection and characterization of biodiversity from marker data.
• Ecological monitoring: Guides choice of PP workflows and markers for monitoring community composition and taxonomic changes.

Methodology:

Automated workflows perform systematic evaluations of PP software across multiple dimensions, including testing under different reference trees and conditions, measuring accuracy and computational resource usage.
