Bio-Data Interpreter
Expert-level bioinformatics data interpretation skill for genomics, proteomics, metagenomics, and phage biology research.
Core Capabilities
1. Sequence Analysis
- Genome/gene sequence statistics (length, GC content, N50, L50)
- Coding density and gene prediction quality
- Codon usage bias and adaptation indices
- Sequence alignment interpretation (identity, coverage, e-value)
2. Assembly Quality Assessment
- Contiguity metrics: N50, L50, largest contig, total length
- Completeness: BUSCO scores, CheckM completeness/contamination
- Misassembly detection and interpretation
3. Annotation Interpretation
- Gene function annotation (GO, KEGG, COG, Pfam)
- Pathway enrichment analysis
- Virulence factor and antibiotic resistance gene detection
- Mobile genetic element identification
4. Phylogenetic Analysis
- Tree topology interpretation
- Bootstrap support evaluation
- Evolutionary distance and divergence
- Taxonomic classification (GTDB, NCBI taxonomy)
5. Metagenomics
- Community composition (alpha/beta diversity)
- Taxonomic profiling (species, genus abundance)
- Binning quality (completeness, contamination)
- Functional metagenomics interpretation
6. Phage Biology
- Phage genome annotation (structural, replication, lysis genes)
- Host prediction methods and confidence
- Lifestyle prediction (temperate vs lytic)
- Phage-host interaction networks
- Prophage identification and boundaries
Data Type Recognition

Output Interpretation Patterns
CheckM Output:
Completeness: 98.5% → High-quality MAG (>90%)
Contamination: 1.2% → Low contamination (<5%)
BUSCO Output:
C:95.2%[S:93.1%,D:2.1%],F:2.3%,M:2.5%
→ Complete: 95.2%, Single-copy: 93.1%, Duplicated: 2.1%
→ Fragmented: 2.3%, Missing: 2.5%
→ Interpretation: High-quality assembly
BLAST E-value:
- E < 1e-50: Very strong hit
- E < 1e-10: Strong hit
- E < 1e-5: Moderate hit
- E > 1e-5: Weak hit, interpret with caution

Key Metrics Reference
Genome Assembly Quality
| Metric | Good | Acceptable | Poor |
|---|
| N50 | >1 Mb | 100kb-1Mb | <100kb |
| BUSCO Complete | >95% | 80-95% | <80% |
| CheckM Completeness | >90% | 70-90% | <70% |
| CheckM Contamination | <5% | 5-10% | >10% |
MAG Quality Tiers (MIMAG)
- High-quality: >90% complete, <5% contamination, presence of 5S/16S/23S rRNA and tRNA
- Medium-quality: ≥50% complete, <10% contamination
- Low-quality: <50% complete or >10% contamination
Diversity Indices
- Shannon Index (H'): 0-4+, higher = more diverse
- Simpson Index (1-D): 0-1, higher = more diverse
- Chao1: Richness estimator, accounts for rare species
Scientific Communication Guidelines
When interpreting results:
- State the metric and its value
- Provide context (what is typical, what is good/bad)
- Explain biological significance
- Note any caveats or limitations
- Suggest follow-up analyses if needed
