来自 SKILL.md 的关键信息

2 min

核心说明

  • Python:cooltools.eigs_cis(clr,gc_cov) ,用于 eigenvector decomposition。
  • Identify /B compartments ,面向 my Hi-C data" → Decompose contact matrix ,通过 eigenvector analysis to classify chromatin into active ( ) 、 inactive (B) compartments. Python:cooltools.eigs_cis(clr,gc_cov) ,用于 eigenvector decomposition。
  • 检测 /B compartments ,面向 Hi-C contact matrices。
  • view_df = bioframe.make_viewframe(clr.chromsizes)。

原始文档

SKILL.md 摘录

Compute Compartment Eigenvectors

clr = cooler.Cooler('matrix.mcool::resolutions/100000')

## Compute expected values first

expected = cooltools.expected_cis(clr, view_df=view_df, ignore_diags=2)

## Compute eigenvector decomposition (compartments)

eigenvector_track = cooltools.eigs_cis(
    clr,
    view_df=view_df,
    phasing_track=None,  # Or provide GC content track
    n_eigs=3,
)

适用场景

  • 适合在identifying /B compartments ,面向 Hi-C data时使用。

不适用场景

  • Do not rely on this catalog entry alone ,用于 installation 或 maintenance details。
