How to color a pangenome graph using SN:Z: fields

[atomemeteore]

Hello everyone,

I recently made a pangenome using an input text file containing the locations of 3 multifasta corresponding to the genomes I want to work with.

The png I obtained was 3 paths corresponding to each genome.

I was wondering if there was a way to color the segment of each path according to their chromosome appartenance ? I noticed that each segment was affiliated to a chromosome with their SN:Z: field.

Thank you very much

How exactly did you make your png?

I converted my gfa file to og file format (odgi build command) and transformed this file into png image (odgi viz command)
But odgi only has color options based on paths and not nodes

I think you want to move this discussion here https://github.com/pangenome/odgi/issues

I'll do that, thank you
