bin-level-sequencing-depth-calculation

bin-level-sequencing-depth-calculation is a skill for Claude Code, Codex from HolobiomicsLab/asb-skill-collections. It costs 68 tokens per session (1,431 once invoked), scanned A, original, Apache-2.0.

A tool for counting raw Hi-C or micro-C sequencing reads in each genomic bin from a cooler contact-matrix file. It produces a track or table showing coverage across the genome.

In plain words
What is it for?
Use it to assess Hi-C or micro-C data quality, find poorly sequenced genomic regions, and prepare bin-level weights for normalization.
Why use it?
It helps reveal regions with unusually low or uneven sequencing coverage before analysis or normalization.

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

bin-level-sequencing-depth-calculation 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 10d 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

Compute per-bin sequencing depth (coverage) from a cooler Hi-C contact matrix using cooltools.coverage(), producing a bedGraph or tabular track of read counts per genomic bin. This enables quality assessment and normalization of high-resolution chromosome conformation capture datasets.

When to use

You have a cooler file (.cool or .mcool) from a Hi-C or micro-C experiment and need to quantify the total number of sequencing reads assigned to each genomic bin to assess coverage uniformity, identify poorly-sequenced regions, or prepare bin-level weights for downstream normalization. Specifically useful when the cooler object is already loaded in memory and you want to export coverage as a track file (bedGraph or tabular CSV/TSV).

When NOT to use

  • Input data is already a normalized or log-transformed contact matrix (coverage calculation assumes raw counts).
  • You need trans (inter-chromosomal) coverage only; cooltools.coverage() by default computes cis (intra-chromosomal) counts.
  • The cooler file has no valid bin or contact data (e.g., empty or corrupted cooler).

Inputs

  • cooler contact matrix object (loaded via cooler.Cooler() or cooler.open_cooler())
  • Hi-C or micro-C cooler file (.cool or .mcool format)

Outputs

  • bedGraph file or tabular track (CSV/TSV) with columns: chromosome, start, end, coverage
  • optionally, cis count column stored in cooler HDF5 metadata

How to apply

Load a cooler contact matrix object using the cooler library, then call cooltools.coverage() on it to compute per-bin sequencing depth. The function signature permits optionally storing total cis counts as a new column in the cooler HDF5 file. After computation, export the resulting coverage array (bin coordinates + coverage values) to bedGraph or tabular format (CSV/TSV). Validate the output by checking that the number of rows matches the total bin count in the cooler object's bins table, and that coverage values are non-negative integers or floats reflecting read accumulation per bin.

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.

bin-level-sequencing-depth-calculation is a skill published in the GitHub repository HolobiomicsLab/asb-skill-collections (15 stars, last pushed 4d ago), licensed Apache-2.0. It adds 68 tokens to every session and 1,431 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 2026-08-30.
