Shotgun Metagenomics Profiler

Comprehensive shotgun metagenomics analysis combining taxonomic classification, antimicrobial resistance gene detection, and functional pathway profiling from paired-end FASTQ files.

What it does

Takes paired-end FASTQ files (R1, R2) or a single concatenated FASTQ as input
Runs Kraken2 taxonomic classification against a standard database (e.g., Standard-8, PlusPF)
Refines abundances with Bracken at species level (read re-estimation)
Detects antimicrobial resistance genes with RGI against the CARD database
Classifies detected ARGs by WHO critical priority pathogen association
Optionally runs HUMAnN3 for functional pathway profiling (MetaCyc + UniRef)
Calculates alpha diversity metrics from Bracken-adjusted species abundances:
- Shannon diversity index: H = -sum(p_i * ln(p_i)), where p_i is the proportion of classified reads assigned to species i
- Simpson diversity index: D = 1 - sum(p_i^2)
- Pielou evenness: J = H / ln(S), where S is the number of species detected
- Species richness: S = number of distinct species with at least 1 assigned read
Generates four publication-quality figures:
- Figure 1: Taxonomy bar chart, top 20 species by relative abundance
- Figure 2: Resistome heatmap, ARG families by drug class with abundance
- Figure 3: WHO-critical ARG summary, priority-tier breakdown of detected resistance genes
- Figure 4: Alpha diversity summary (Shannon, Simpson, Pielou in a panel)
Produces a full reproducibility bundle (commands.sh, environment.yml, checksums.sha256)

Why this exists

If you ask a general AI to "analyse a metagenome," it will:

Not know which Kraken2 database to use or how to set confidence thresholds
Hallucinate Bracken parameters for read-length and taxonomic level
Miss the connection between detected ARGs and WHO priority pathogen lists
Skip HUMAnN3 entirely (or misconfigure its database paths)
Produce a single bar chart with no resistance context
Skip diversity metric calculations (Shannon, Simpson, Pielou)
Not provide a reproducibility bundle

This skill encodes the correct methodological decisions:

Kraken2 confidence threshold of 0.2 (reduces false positives in environmental samples)
Bracken re-estimation at species level with minimum 10 reads
RGI MAIN with "Perfect" and "Strict" hit criteria only (no "Loose" hits)
WHO Critical Priority Pathogen list mapped to detected ARG families
HUMAnN3 with MetaCyc stratification for pathway-level functional context
Thread count auto-detected from available CPUs
Full reproducibility bundle for every run

Validated On

The skill works with any shotgun metagenome but has been validated on:

Peru sewage metagenomics study (6 samples, 3 collection sites: Lima, Cusco, Iquitos)
Environmental sewage samples with mixed microbial communities
Read depths ranging from 2M to 15M paired-end reads per sample

WHO-Critical ARG Detection

A key feature is the classification of detected resistance genes by WHO priority tier:

Priority	Pathogen	Resistance
Critical	Acinetobacter baumannii	Carbapenem-resistant
Critical	Pseudomonas aeruginosa	Carbapenem-resistant
Critical	Enterobacteriaceae	Carbapenem-resistant, 3rd-gen cephalosporin-resistant
High	Enterococcus faecium	Vancomycin-resistant
High	Staphylococcus aureus	Methicillin-resistant, vancomycin-resistant
High	Helicobacter pylori	Clarithromycin-resistant
High	Campylobacter	Fluoroquinolone-resistant
High	Salmonella spp.	Fluoroquinolone-resistant
High	Neisseria gonorrhoeae	3rd-gen cephalosporin-resistant, fluoroquinolone-resistant
Medium	Streptococcus pneumoniae	Penicillin-non-susceptible
Medium	Haemophilus influenzae	Ampicillin-resistant
Medium	Shigella spp.	Fluoroquinolone-resistant
