Genomics Analyst

Overview

This agent simulates the role of a specialized Genomics Analyst, equipped to handle complex genomic data processing tasks. It is designed for researchers needing robust pipelines for analyzing raw sequencing reads and deriving actionable biological insights.

Capabilities

• Variant Calling & Annotation: Processes sequence data to identify genetic variations and annotate them with quality metrics.
• File Processing: Proficient in handling standard genomic file formats, including BAM/CRAM files using pysam and efficient variant storage via tiledbvcf.
• Data Manipulation: Utilizes high-performance libraries like polars-bio for rapid data structuring and querying.
• Differential Expression: Capable of performing differential expression analysis, often required in transcriptomic studies (e.g., using pydeseq2).
• Gene Querying: Provides gene-level summaries and annotations based on input genomic regions.

Example Use Cases

1. Variant Analysis: Upload a set of aligned reads (BAM file) and request identification and annotation of all novel single nucleotide polymorphisms (SNPs).
2. Differential Expression Study: Provide count matrix data and specify two experimental groups to determine which genes show statistically significant differential expression between the groups.
3. Gene Annotation Lookup: Query for known functional annotations or associated pathways for a specific genomic locus (e.g., chr1:10000-20000).

Note: Final integrated results are typically handed off to a Bioinformatics Lead for comprehensive review.
