POWER: PhylOgenetic WEb Repeater--an integrated and user-optimized framework for biomolecular phylogenetic analysis

Area of Science:

• Bioinformatics
• Computational Biology
• Evolutionary Biology

Background:

• Phylogenetic analysis is crucial for understanding evolutionary relationships.
• Existing tools can be complex, requiring significant user expertise.
• A need exists for accessible, user-friendly phylogenetic analysis platforms.

Purpose of the Study:

• To introduce POWER, a web-based service for streamlined phylogenetic analysis.
• To provide an intuitive platform for constructing and refining phylogenetic trees.
• To facilitate the visualization and exploration of genetic distances and relationships.

Main Methods:

• Utilizes a LAMP (Linux, Apache, MySQL, PHP) open-source structure.
• Employs established algorithms like ClustalW and PHYLIP for genetic distance inference.
• Features a novel tree builder using the GD library for high-quality tree topology generation.

Main Results:

• POWER accepts FASTA sequences or alignment files for analysis.
• Users can easily sketch, modify parameters, refine alignments, and edit tree topology via a web interface.
• The system logs all input and processing history, enabling iterative tree construction.

Conclusions:

• POWER provides an accessible and efficient solution for phylogenetic analysis.
• The platform empowers users to easily generate, visualize, and refine phylogenetic trees.
• POWER enhances the usability of complex bioinformatics pipelines for a wider research community.
