ngs-runtime-env
GitHub用于NGS工作流的环境检查技能。验证工具、Python包及参考数据库是否存在，生成安装计划，支持容器隔离环境，确保在用户明确请求前不修改系统或自动安装。

NGS Runtime Environment
Use this skill whenever an NGS workflow needs package checks, install planning, or runtime validation.
Existence Check Order
- Check executables on
PATHwithcommand -vorshutil.which. - Check Python imports for Python-backed tools.
- Check active package managers with
conda list,mamba list,micromamba list, orpip show. - If requested, check package indexes or container registries.
- Emit an install plan before installing.
- Install only when explicitly requested by the user.
Do not modify system Python. Prefer isolated conda/mamba environments or containers.
Script
From the repo root:
python plugins/ngs-analysis/scripts/ngs_preflight.py --list
python plugins/ngs-analysis/scripts/ngs_preflight.py --tool fastqc --emit-install-plan
python plugins/ngs-analysis/scripts/ngs_preflight.py --profile local_light --emit-install-plan
python plugins/ngs-analysis/scripts/ngs_preflight.py --pipeline dna_variant_calling --network-checks --emit-install-plan
python plugins/ngs-analysis/scripts/ngs_preflight.py --pipeline shotgun_metagenomics --manager micromamba --install-plan-outdir runtime_readiness/shotgun_install
Use --install-plan-outdir when a user needs a reviewable permission handoff. It writes install_plan.json as the canonical machine-readable plan and install_commands.sh as a guarded shell companion generated from the same plan. The shell companion is review-only by default; it exits without installing unless NGS_RUN_INSTALL_COMMANDS=1 is set after explicit user approval.
Check reference and database bundle readiness separately from executable readiness:
python plugins/ngs-analysis/scripts/ngs_reference_manager.py list
python plugins/ngs-analysis/scripts/ngs_reference_manager.py check --kind reference --bundle grch38_core --root /refs/GRCh38
python plugins/ngs-analysis/scripts/ngs_reference_manager.py explain-missing --kind database --bundle kraken2_standard --root /db/kraken2/standard
python plugins/ngs-analysis/scripts/ngs_reference_manager.py plan --pipeline shotgun_metagenomics --include-optional --outdir resource_readiness/shotgun
python plugins/ngs-analysis/scripts/ngs_reference_manager.py setup-plan --pipeline shotgun_metagenomics --include-optional --outdir resource_readiness/shotgun_setup
python plugins/ngs-analysis/scripts/ngs_reference_manager.py plan --pipeline atacseq --genome-build GRCh38 --bundle-root grch38_core=/refs/GRCh38 --outdir resource_readiness/atac
python plugins/ngs-analysis/scripts/ngs_reference_manager.py inventory --outdir resource_readiness/inventory
python plugins/ngs-analysis/scripts/ngs_reference_manager.py lock --outdir resource_readiness/lock --include-checksums
python plugins/ngs-analysis/scripts/ngs_reference_manager.py verify-lock --lockfile resource_readiness/lock/resource_lock.json --outdir resource_readiness/lock_verify --fail-on-mismatch
python plugins/ngs-analysis/scripts/ngs_reference_manager.py check-all --kind database --output resource_readiness/database_audit.json
Use plan before claiming that a reference- or database-heavy workflow is runnable. The plan output writes resource_plan.json, resource_manifest.tsv, resource_env.sh, resource_readiness.md, and setup-plan artifacts; missing required bundles are blocking, while optional bundles such as Bracken/HUMAnN or HOMER motif resources should stay explicit.
Use setup-plan when the user needs an actionable resource/database setup checklist without running an assay. It writes resource_setup_plan.json, resource_setup_plan.tsv, resource_setup_plan.md, and resource_setup_commands.sh. The shell skeleton keeps setup hints commented by default, so large reference/database downloads remain deliberate and reviewable.
Use inventory when the user needs a broader resource/database audit across the plugin. It writes resource_inventory.json, resource_inventory.tsv, resource_env.sh, and resource_dashboard.md, including missing files, env vars, setup hints, license notes, and pipeline usage for every known bundle.
Use lock after resources are ready for a project or handoff. It snapshots the resource inventory into resource_lock.json, resource_lock.tsv, and resource_lock.md; verify-lock compares the lockfile against current local paths and writes a drift report before reruns.
The nf-core adapter performs the same resource gate automatically unless --skip-resource-plan is supplied:
python plugins/ngs-analysis/scripts/run_nfcore_pipeline.py --pipeline taxprofiler --sample-sheet samples.csv --profile docker --bundle-root kraken2_standard=/db/kraken2/standard --include-optional-resources
The direct bulk RNA-seq counts/QC, scRNA FASTQ-to-count, generic DNA, germline DNA, somatic DNA, UMI panel, ATAC, ChIP/CUT&RUN, amplicon, and shotgun backend runners also emit run-local resources/ readiness bundles. These direct runners use advisory resource checks by default so custom or reduced local inputs can still be planned; add --require-resource-plan when missing registered bundles should block readiness.
Use --install-missing --yes only after explicit user approval:
python plugins/ngs-analysis/scripts/ngs_preflight.py --pipeline fastq_qc --manager mamba --install-missing --yes
Install Strategy
Prefer these patterns:
- nf-core workflows: install/check
nextflow; use Docker/Singularity/Apptainer profiles for process tools. - local execution: install/check
snakemake; usemambaormicromambaenvironments and avoid containers by default. - small QC tools: install with
mambaormicromambafromconda-forgeandbioconda. - Python analysis packages: install in a dedicated environment, not global Python.
- large databases and references: estimate size and check existing paths before downloading.
- pipeline resource plans: use
--bundle-root bundle=/pathor the registryroot_envvariables so downstream runs can cite the exact local bundle roots.
Report
Summarize:
- present tools and paths
- missing tools
- package-index checks, if performed
- suggested install commands
- tools that are proprietary, EULA-bound, cloud-bound, or database-heavy
