bio-copy-number-subclonal-copy-number

bio-copy-number-subclonal-copy-number is a skill for Claude Code, Codex from PKU-YuanGroup/OpenAI4S. It costs 144 tokens per session (3,547 once invoked), scanned A, a copy of bio-copy-number-subclonal-copy-number, MIT.

A tumour-genome analysis workflow for finding copy-number changes present in only some cancer cells. Copy number means how many copies of a DNA region cells carry; mixed cell populations can make this appear as a non-integer value.

In plain words
What is it for?
Use it to resolve clonal and subclonal copy-number changes, detect whole-genome doubling, estimate the fraction of cancer cells carrying an alteration, and study how tumour cell populations changed over time.
Why use it?
It helps distinguish real subpopulations and tumour evolution from measurement noise in bulk sequencing data.

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

bio-copy-number-subclonal-copy-number 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 9d 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.

Origin

This is a copy

98% identical to bio-copy-number-subclonal-copy-number — 12 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 220 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Version Compatibility

Reference examples tested with: R 4.3+ with Battenberg 2.2.10+ and TitanCNA 1.40+, MEDICC2 1.0+, Python 3.10+; impute2/Beagle phasing reference panels.

Before using code patterns, verify installed versions match. If versions differ:

  • R: packageVersion('Battenberg') / 'TitanCNA') then ?function
  • CLI: medicc2 --help
  • Battenberg is GitHub-only (Wedge-lab/battenberg) and needs a 1000 Genomes impute/phasing reference and allele-counter; confirm reference data is installed

Battenberg and TITAN both consume allele-specific data (logR + BAF at heterozygous SNPs); they cannot run on relative copy ratio alone.

Subclonal Copy Number and Tumor Evolution

"This copy number is non-integer — is it noise, or are there subclones" -> A tumor is a mixture of cell populations. When a copy-number change is present in only some cancer cells, bulk sequencing averages it into a non-integer state. A long non-integer segment is not noise — it is a subclonal copy-number alteration, and resolving it reveals the tumor's clonal architecture.

  • R: Battenberg (phased clonal + subclonal CN), TitanCNA (HMM mixture of cell populations)
  • CLI: medicc2 (whole-genome-doubling-aware copy-number phylogenies)
  • Input: allele-specific data — see allele-specific-copy-number for the clonal layer

Clonal vs Subclonal — What the Tools Output

Concept Meaning
Clonal CNA Present in all cancer cells; one copy-number state per segment
Subclonal CNA Present in a fraction of cancer cells; the segment needs two states plus a fraction
Cancer cell fraction (CCF) Fraction of cancer cells carrying the event
Mirrored subclonal allelic imbalance Different subclones lose opposite haplotypes of the same region

Battenberg fits a clonal allele-specific profile (ASCAT internally), then where a segment fits poorly as a single integer state, it models it as a mixture of two states with a subclonal fraction. TITAN uses an HMM whose states span multiple clonal clusters, jointly estimating per-cluster cellular prevalence. Both need haplotype phasing — subclonal allelic imbalance is only resolvable when SNPs are phased.

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.
