Genomics and Epigenomics Data Processing

Production-ready computational skill for processing and analyzing epigenomics data. Combines local Python computation (pandas, scipy, numpy, pysam, statsmodels) with ToolUniverse annotation tools for regulatory context. Designed to solve BixBench-style questions about methylation, ChIP-seq, ATAC-seq, and multi-omics integration.

When to Use This Skill

Triggers:

• User provides methylation data (beta-value matrices, Illumina arrays) and asks about CpG sites
• Questions about differential methylation analysis
• Age-related CpG detection or epigenetic clock questions
• Chromosome-level methylation density or statistics
• ChIP-seq peak files (BED format) with analysis questions
• ATAC-seq chromatin accessibility questions
• Multi-omics integration (expression + methylation, expression + ChIP-seq)
• Genome-wide epigenomic statistics
• Questions mentioning "methylation", "CpG", "ChIP-seq", "ATAC-seq", "histone", "chromatin", "epigenetic"
• Questions about missing data across clinical/genomic/epigenomic modalities
• Regulatory element annotation for processed epigenomic data
