bio-data-visualization-circos-plots SKILL.md skillA
bio-data-visualization-circos-plots from pku-yuangroup/openai4s is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Build circular genome visualizations using circlize (R), pyCirclize (Python), or Circos (Perl CLI) with ideogram tracks, multi-data tracks (scatter, histogram, heatmap), chord/link arcs for interactions, and explicit circos.clear() between plots. Covers when circular is appropriate vs when Cartesian wins (Cleveland-McGill 1984), karyograms, and chromosome adjacency in chord diagrams. Use when adjacency on the circle conveys meaning — chromosome-level overview, structural variants, Hi-C…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
## Version Compatibility
Reference examples tested with: circlize 0.4.16+ (R), pyCirclize 1.4+ (Python), Circos 0.69-9 (Perl CLI), ComplexHeatmap 2.18+ (uses circlize for color mapping).
Before using code patterns, verify installed versions match. If versions differ:
- R: `packageVersion('<pkg>')` then `?function_name`
- Python: `pip show <package>` then `help(module.function)`
If code throws ImportError, AttributeError, or TypeError, introspect the installed package and adapt the example to match the actual API rather than retrying.
# Circular Genome Plots (Circos)
**"Make a circos plot"** -> Render genome chromosomes around a circle with stacked tracks (histogram, scatter, heatmap) and arcs/chords showing interactions. Krzywinski 2009 *Genome Res* 19:1639 introduced the genre for genome-scale comparative views. The single decision that matters: **does the circular layout convey meaning that Cartesian cannot?**
- R: `circlize::circos.initializeWithIdeogram` + `circos.genomicTrack*` (Gu 2014)
- Python: `pyCirclize.Gcircle`
- CLI: Circos (Perl); config-driven; most flexible but steepest learning

How to install
mdr add pku-yuangroup/openai4s/bio-data-visualization-circos-plots@sha256:4ffdc05bc51025b5The line at the top of this page pins the label git:20260821.2d1b678, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
