Which alignment tools are supported by this skill?

The skill primarily utilizes MAFFT for multiple sequence alignment, offering various modes ranging from high-speed heuristics for large datasets to high-accuracy local pair alignments for smaller sets.

How does it handle very large datasets?

For datasets with more than 1,000 sequences where traditional maximum likelihood might be too slow, the skill provides an integrated FastTree workflow for approximate ML inference.

Does it include automatic model selection?

Yes, the IQ-TREE 2 implementation automatically performs model selection (ModelFinder) to identify the best-fit substitution model for your specific data.

Can this skill handle both DNA and protein sequences?

Yes, it includes specialized logic and model selection for both nucleotide (DNA) and amino acid (protein/proteomic) sequence data.

What visualization options are available?

The skill uses the ETE3 library to render trees in rectangular or circular modes, color-code taxa by group, and export results to standard image formats like PNG.

데이터 과학 및 ML

Automates the reconstruction and analysis of evolutionary relationships using industry-standard bioinformatics tools like MAFFT and IQ-TREE.

This skill provides a comprehensive pipeline for phylogenetic research, enabling users to perform multiple sequence alignment, tree inference, and visualization within a unified workflow. By integrating tools like MAFFT for alignment, IQ-TREE 2 for maximum likelihood estimation, and ETE3 for tree manipulation, it streamlines complex tasks such as viral phylodynamics, protein family analysis, and molecular clock studies. It is specifically designed for researchers and bioinformaticians who need to infer common ancestry and evolutionary patterns from large-scale genomic or proteomic datasets.
