Cn_signatures_from_ichorcna #63

SaraPotente · 2026-02-05T14:17:40Z

Description

After the integration of ichorCNA in the solid_biopsy workflow, with this PR we extend the pipeline by enabling copy number signature quantification from ichorCNA outputs, ensuring compatibility with downstream CIN signature.

Specifically, this PR:

Adds a formatting step to standardize ichorCNA segmentation outputs.
Selects and renames the required columns to match the expected input format for copy number signature tools.
Integrates the new formatting process into the existing solid_biopsy → ichorCNA workflow.

This allows copy number signatures to be computed consistently from ichorCNA results within the solid_biopsy setting.
