alignment-and-mapping

alignment-and-mapping is a skill for Claude Code, Codex from zongtingwei/Bioclaw_Skills_Hub. It costs 23 tokens per session (869 once invoked), scanned A, original, MIT.

A workflow for preparing biological sequencing data by matching short DNA or RNA readings to a reference genome or transcriptome. It also sorts and indexes the resulting files and records mapping statistics.

In plain words
What is it for?
Use it when working with FASTQ, BAM, or CRAM files, especially to create aligned files, indexes, mapping metrics, and quality reports for later analysis.
Why use it?
It turns raw or partly processed sequencing files into organized results that other analysis steps can use, while adding quality checks and tool-version checks.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

alignment-and-mapping scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Alignment And Mapping

Version Compatibility

Reference examples assume recent stable releases of the preferred tools, especially samtools and the other tools listed below.

Before using code or command patterns, verify installed versions match the environment:

  • Python: python -c "import <module>; print(<module>.__version__)"
  • CLI: <tool> --version
  • If signatures differ, inspect the installed help or API and adapt the pattern instead of retrying unchanged.

Overview

Workflow for read alignment, sorting, indexing, mapping statistics, and downstream-ready alignment artifacts.

When To Use This Skill

  • use when the task is sequence alignment or alignment file preparation
  • use when FASTQ files must be mapped to a genome or transcriptome
  • use when BAM or CRAM files and mapping metrics are the expected outputs

Quick Route

  • If the input is raw or minimally processed data, start with validation and QC before any modeling.
  • If the input is already processed, skip directly to the first workflow step that matches the user goal.
  • If the user asks for a biological conclusion, always produce at least one QC or confidence artifact alongside the final result.

Progressive Disclosure

  • Read references/technical_reference.md when you need deeper tool-selection rules, environment adaptation notes, or extra validation guidance.
  • Keep SKILL.md as the main execution path and load the reference file only when the task or failure mode needs the extra detail.

Default Rules

  • Prefer Python-first workflows unless the task explicitly requires something else.
  • Keep intermediate and final outputs separated.
  • Record software versions, reference builds, and key parameters when they affect interpretation.
  • Favor reproducible tables and figures over one-off interactive-only outputs.

Expected Inputs

  • FASTQ files
  • reference genome or transcriptome
  • alignment indexes

Expected Outputs

  • sorted and indexed alignments
  • mapping metrics
  • downstream-ready BAM or CRAM files

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
