eigenvector-digitization-into-compartment-bins

eigenvector-digitization-into-compartment-bins is a skill for Claude Code, Codex from HolobiomicsLab/asb-skill-collections. It costs 59 tokens per session (1,466 once invoked), scanned A, original, Apache-2.0.

A preprocessing workflow for Hi-C data, which measures contact frequency between genomic regions, that turns continuous eigenvector scores into discrete A/B compartment groups.

In plain words
What is it for?
It helps classify Hi-C bins into two to five compartment levels before saddle analysis or compartment contact comparisons.
Why use it?
Downstream saddle plots and compartment comparisons need genomic bins assigned to categories rather than left as ungrouped numerical scores.

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

eigenvector-digitization-into-compartment-bins 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.

Summary

Discretize continuous eigenvector values from Hi-C compartment analysis into categorical bins (typically 2–5 levels) representing A/B compartment states using quantile or fixed thresholds. This preprocessing step converts a continuous genomic track into a discrete compartment assignment required for downstream saddle plot analysis and compartment interaction quantification.

When to use

You have computed eigenvector values from a prior eigs_cis calculation on a cooler Hi-C matrix and need to classify genomic regions into discrete A/B compartment categories before performing saddle analysis or computing compartment-level contact asymmetry metrics.

When NOT to use

  • Eigenvector values are missing or NaN for large fractions of the genome (no meaningful bins can be defined)
  • The eigenvector track and cooler have mismatched bin resolutions or genomic coordinates
  • You are performing continuous (non-binned) compartment strength analysis and do not need discrete categorical assignments

Inputs

  • cooler Hi-C matrix file (h5 format)
  • eigenvector track (1D numpy array or bedGraph, indexed by genomic bins)
  • binning parameters (bin edges, quantile thresholds, or bin count)

Outputs

  • digitized compartment track (1D array of integer bin labels, same length as input eigenvector)
  • bin boundary definitions or threshold values used for digitization

How to apply

Load the eigenvector track (a 1D array indexed by genomic bins) alongside the cooler Hi-C object. Apply cooltools.digitize to partition eigenvector values according to quantile-based or fixed thresholds into 2–5 discrete bins, each representing a compartment strength class. The choice of binning strategy (quantile vs. fixed threshold) should reflect whether you prioritize balanced bin populations or absolute eigenvector magnitude cutoffs. Validate that the output digitized track has the correct length (matching the number of bins in the cooler) and that bin labels are numeric (typically 0–4). This discretized track is then passed to cooltools.saddle to aggregate contact frequencies by compartment pair.

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.

eigenvector-digitization-into-compartment-bins is a skill published in the GitHub repository HolobiomicsLab/asb-skill-collections (15 stars, last pushed yesterday), licensed Apache-2.0. It adds 59 tokens to every session and 1,466 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
