ATAC-seq Peaks QC

Use this skill for ATAC-seq accessibility analysis from FASTQ or BAM. If the assay is ChIP-seq, CUT&RUN, CUT&Tag, or antibody-targeted enrichment, use ngs-chip-cutrun-peaks-qc.

Essential Inputs

Confirm:

  • FASTQ/BAM inputs and paired-end status
  • organism, genome build, blacklist, and mitochondrial contig names
  • biological replicates, conditions, batches, and sample metadata
  • whether the target is QC only, peaks, consensus peaks, bigWigs, or differential accessibility
  • whether Tn5 shifting is handled by the chosen workflow
  • desired peak caller and downstream matrix generation

Route

Prefer nf-core/atacseq for full reproducible processing. Use direct MACS2 only when BAMs are already aligned, duplicate/blacklist handling is known, and the user wants focused peak calling.

Preflight command:

python plugins/ngs-analysis/scripts/ngs_preflight.py --pipeline atacseq_peaks_qc --emit-install-plan

For compact read-level intake/QC, use the shared epigenomics execution package:

python plugins/ngs-analysis/scripts/run_fastq_assay_package.py \
  --lane epigenomics_peaks \
  --sample-sheet atac_samples.csv \
  --execute

For local-light ATAC alignment, peaks, FRiP, TSS, bigWig tracks, and consensus peaks from FASTQ or prepared BAMs, use the dedicated ATAC runner:

python plugins/ngs-analysis/scripts/run_atacseq_peaks_qc.py \
  --sample-sheet atac_samples.csv \
  --bowtie2-index /refs/GRCh38/bowtie2/genome \
  --genome-size hs \
  --blacklist-bed /refs/GRCh38/blacklists/encode_blacklist.bed \
  --tss-bed /refs/GRCh38/tss.bed \
  --execute

This runner emits qc/atacseq_qc_summary.{tsv,json}, qc/atacseq_qc_dashboard.html, native SVG FRiP/peak and insert-size plots, browser-track handoff files under tracks/, and TSS profile/heatmap commands when --tss-bed is supplied. Add --run-motifs --motif-genome <genome> when HOMER motif enrichment should be part of the backend run.

It also emits resources/resource_plan.json, resource_manifest.tsv, resource_env.sh, and resource_readiness.md. The resource check is advisory by default for local-light runs; add --genome-build, --bundle-root <bundle>=<path>, and --require-resource-plan when missing registered reference bundles should block readiness.

For nf-core execution, use plugins/ngs-analysis/scripts/run_nfcore_pipeline.py --pipeline atacseq.

QC Gates

Review before biological interpretation:

  • read depth, alignment rate, duplicate rate, and mitochondrial fraction
  • insert-size periodicity/nucleosome pattern
  • TSS enrichment and FRiP score when available
  • blacklist overlap and peak count per sample
  • replicate concordance and consensus peak support

Do not proceed to differential accessibility if replicate quality or metadata is insufficient.

Outputs

Produce:

  • sample sheet and workflow command/profile
  • QC summary and failed-sample flags
  • narrowPeak/BED peak sets, consensus peaks, bigWigs, browser-track manifests, browser-track preview HTML, native QC dashboard/SVG plots, TSS plots, and peak-count matrix when requested
  • motif summary files when a motif backend is requested
  • differential-accessibility design and contrasts if applicable
  • caveats for low TSS enrichment, high mitochondrial reads, weak replicate concordance, or poor FRiP

概要と使いどころ

Make data visualizations accessible and inclusive. Use when the user needs chart or diagram accessibility guidance, text alternatives for complex visuals, color and contrast review, keyboard support, reduced-motion behavior for animation or parallax, or an accessibility QA workflow for exported figures, UML-like diagrams, and dashboards.

Apply consistent photo adjustments across a set of images so they look like they were edited together. Use this skill whenever the user says "make my photos look cohesive", "give all these the same style", "apply a warm and golden feel to all of these", "make this cinematic", "match the look across my photos", "edit all my travel photos the same way", "batch edit these", "make these consistent", "fix my phone photos", or uploads a folder of photos and wants a unified, polished result. Also triggers for requests like "apply a preset to all of these", "make these look professional", or "they were shot in mixed lighting — can you fix them all". Outputs direct final image URLs plus an in-chat preview grid and optional Firefly Board link. Access: 🔐 Signed-In required | Gen AI: ❌

Resize, crop, or export any image or video into platform-ready social media assets using Adobe Creative Cloud tools. Use this skill when a user wants to prepare a photo, image, or video for one or more social platforms — Instagram, TikTok, LinkedIn, Facebook, YouTube, Snapchat, Pinterest, Threads, or X/Twitter. Triggers on: "prepare my image for Instagram", "resize for TikTok", "get this ready to post", "make versions for all platforms", "social media sizes", "crop for stories", "export for LinkedIn", "resize my video for social", "make social media assets", or any request to adapt a photo or video for specific platforms. Handles subject-aware cropping, AI canvas expansion, test previews before full runs, and same-ratio video resizing.

Create any visual design using Adobe Express templates — flyers, posters, social media posts (Instagram, Facebook, LinkedIn), business cards, invitations, greeting cards, resumes, cover letters, brochures, newsletters, certificates, presentations, YouTube thumbnails, email headers, logos, menus, and labels. Use this skill whenever the user wants to make, design, or build any visual — even if they just say "make me a flyer", "design a poster", "I need something for Instagram", "create an event invite", or "make a business card". Also handles browsing templates, editing text, replacing images, changing backgrounds, animating, and exporting designs. Access: 🔐 Signed-In required | Gen AI: ❌ by default — image replacement only where the surface permits generative AI (e.g. Codex); none on Claude

Create a punchy sizzle reel from a video using Adobe Quick Cut. Use this skill whenever a user wants to cut, trim, or shorten a video into highlights — including phrases like "make a sizzle reel", "make a highlight reel", "quick cut this", "cut the best parts", "shorten this video", "make a highlight clip", "summarize this video visually", or any request to produce a shorter edited version of a video. Use this skill for Quick Cut requests before suggesting manual editing in Premiere. Requires the user to upload a video file.
