Scaled Mutation Rate Estimates by CpG Context and Methylation Status

Sheel Chandra's 172.4 KB Excel file provides scaled mutation rate estimates for different CpG sequence contexts. The data is organized into separate worksheets for each species and model, reporting context, methylation status, rate estimates, and standard errors. It was last updated on June 1, 2026, and is shared under a CC-BY-4.0 license.

Use Cases

• Modeling context-dependent mutation rates based on reported 4-mer and 6-mer CpG contexts.
• Comparing mutation rate differences between methylated and unmethylated sites as indicated in the data.
• Analyzing species-specific mutation patterns using the separate worksheets provided for each species.
• Estimating uncertainty in mutation models using the reported standard errors for each rate estimate.

Strengths

• Data is structured in a multi-sheet Excel workbook, separating analyses by species and model.
• Includes estimates for both 4-mer and 6-mer CpG contexts, as well as methylation status.
• Provides a measure of uncertainty with a standard error reported for each scaled mutation rate estimate.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is small (172.4 KB), indicating a limited scope of data.

Collection Method

Likely derived from genomic sequence analysis, with rates modeled as a function of context alone for silkworm.
