# ngs-analysis

Takes BCL or FASTQ input, checks what tools you already have, and routes the run to a public pipeline.

## What it does

The plugin walks sequencing data through a defined route. It inspects the input files first, then asks only the assay questions needed to pick a branch. From there it points at public reproducible pipelines, mostly nf-core, and checks whether the required tools are already on the machine.

Nineteen skills sit inside: a router, a runtime check, BCL demultiplexing, FASTQ QC, DNA variant calling, bulk RNA-seq, single-cell, epigenomics, amplicon and metagenomics. Some lanes run locally. `ngs-fastq-qc` executes FastQC and MultiQC, `ngs-bulk-rnaseq-counts-qc` quantifies transcripts with Salmon, and `ngs-dna-germline-variants` needs a local GATK toolchain plus matching known-sites. Other lanes hand back a plan and readiness artifacts.

Start with `python plugins/ngs-analysis/scripts/ngs_preflight.py --list`. The script looks up executables in `PATH`, runs network checks only when asked, and installs nothing unless you pass `--install-missing --yes`. Reference and database downloads are separate, handled through `ngs_reference_manager.py setup-plan`. One thing to watch: the package is deliberately mixed maturity, and `scrna-seq-qc` falls back to conservative PBMC markers when no matched reference is supplied, so tissue-specific annotation needs review or replacement before wider use.

## When to use it
- split a BCL run folder into FASTQ and review demux metrics
- pick a pipeline for a specific assay without browsing nf-core by hand
- see which tools are installed and get an install plan for the rest
- produce a run report with logs, QC and an input-to-output lineage table
- tell a lane that actually executes locally from one that only plans

## Example prompts
- Run the preflight for bulk RNA-seq and show me the install plan
- I have a BCL run folder — what's next?
- Run QC on these FASTQ files and explain the MultiQC report

# Life Sciences NGS Analysis Plugin

This plugin provides a guided intake and execution layer for common next-generation sequencing analyses. It routes users from BCL or FASTQ files to public, reproducible pipelines while checking local tool availability before installing anything.

## What It Does

- Inspects sequencing inputs before asking questions.
- Asks the minimum assay-specific questions needed to choose an analysis route.
- Prefers public, runtime-installable tools and nf-core workflows where practical.
- Runs tool preflight checks before suggesting downloads or installs.
- Keeps proprietary, credentialed, or cloud-upload paths explicit instead of silently using them.
- Treats preflight as validation before executing approved local workflows where supported.
- Produces timestamped run directories with manifests, validation summaries, logs, QC reports, exact command timing/return-code detail, checksummed artifact indexes, and input-to-output lineage tables.
- Produces native visualization bundles under `visualizations/` when a lane has enough downstream data to plot.

## Included Skills

- `ngs-analysis-router`: top-level intake and routing.
- `ngs-runtime-env`: package/tool existence checks and install planning.
- `ngs-bcl-to-fastq`: BCL run-folder validation, demultiplexing, and demux metric review.
- `ngs-fastq-qc`: FASTQ quality control, trimming decisions, and MultiQC interpretation.
- `ngs-dna-variant-calling`: WGS/WES/panel variant dispatcher.
- `ngs-dna-germline-variants`: germline WGS/WES/panel variant calling and QC.
- `ngs-dna-somatic-variants`: tumor-normal and tumor-only somatic variant calling and QC.
- `ngs-dna-umi-panel-variants`: UMI, duplex, and low-frequency targeted panel workflows.
- `ngs-bulk-rnaseq`: bulk RNA-seq dispatcher.
- `ngs-bulk-rnaseq-counts-qc`: bulk RNA-seq FASTQ-to-count processing and QC.
- `ngs-bulk-rnaseq-differential-expression`: bulk RNA-seq count-matrix differential expression.
- `ngs-scrna-seq`: single-cell or single-nucleus RNA-seq FASTQ-to-count kickoff.
- `scrna-seq-qc`: embedded post-count single-cell QC, annotation, clustering, and UMAP guidance.
- `ngs-epigenomics-peaks`: ATAC-seq, ChIP-seq, CUT&RUN, and CUT&Tag dispatcher.
- `ngs-atacseq-peaks-qc`: ATAC-seq QC, peak, consensus, and differential accessibility workflows.
- `ngs-chip-cutrun-peaks-qc`: ChIP-seq, CUT&RUN, and CUT&Tag QC, control, peak, and differential binding workflows.
- `ngs-amplicon-microbiome`: 16S/18S/ITS/COI amplicon analysis kickoff.
- `ngs-shotgun-metagenomics`: shotgun metagenomics taxonomic and functional profiling kickoff.

## Capability Status

This package is intentionally mixed maturity. Use the status below when deciding what to run versus what to treat as planning guidance.

Local execution lanes:

- `ngs-fastq-qc`: plugin-owned local runner for FASTQ validation, FastQC/MultiQC execution, optional trimming, logs, summaries, and artifact indexes.
- `ngs-bulk-rnaseq-counts-qc`: plugin-owned local runner for bulk RNA-seq FASTQ validation, FastQC/MultiQC, Salmon transcript quantification, TPM/NumReads/effective-length matrices, logs, summaries, and artifact indexes.
- `ngs-bulk-rnaseq-differential-expression`: plugin-owned local runner for count-matrix validation, contrast/replicate checks, automatic DESeq2/edgeR/limma method selection, QC plots, normalized matrices, result tables, logs, summaries, and artifact indexes.
- `ngs-scrna-seq`: plugin-owned local FASTQ-to-count runner for STARsolo-backed scRNA/snRNA count generation.
- `scrna-seq-qc`: post-count QC and annotation guidance, plus a matrix-level runner for 10x-style matrices. The runner uses conservative PBMC marker fallback when no matched reference is provided, so tissue-specific annotation should be reviewed or replaced before broader use.
- `ngs-dna-variant-calling`: plugin-owned BAM/CRAM-to-VCF execution package using samtools/bcftools for focused local checks, with nf-core/sarek still preferred for full WGS/WES/panel workflows.
