Codon Alignment and Selection Pressure Analysis Results

Codon alignments and results from MG94 selection pressure analyses, including dN/dS and absolute REL metrics. The dataset was published by Yao Xiong on the figshare platform and was last updated in April 2026. It comprises multiple file formats including FNA, NWK, TSV, and JSON, totaling 41.7 MB.

Use Cases

• Estimate dN/dS ratios from codon alignments to identify genes under positive or purifying selection.
• Apply absolute REL results to quantify site-specific selection pressure across a phylogenetic tree.
• Use the provided phylogenetic trees (NWK files) to contextualize selection pressure results within an evolutionary framework.
• Analyze codon alignment data (FNA files) for comparative genomics and evolutionary rate calculations.

Strengths

• Data includes results from the established MG94 model for selection pressure analysis.
• Multiple interoperable file formats (FNA, NWK, TSV, JSON) are provided for different analysis stages.
• Dataset is openly licensed under CC-BY-4.0, facilitating reuse and redistribution.

Limitations

• The total number of sequences, genes, or analyzed sites is unknown, limiting assessment of statistical power.
• The dataset is relatively small at 41.7 MB, which may indicate a focused study rather than a broad-scale analysis.
• Specifics on the source organisms, genes, or temporal scope of the genetic data are not provided.
