How to identify which genome the variations in the pan-genome graph originate from

[wk1352313]

We want to use vg to construct a pan-genome. In order to detect variations in the subsequent pan-genome graph and determine which genomes they exist in, we intend to retain the genome source information for the paths within the pan-genome graph. We attempted to add genome information to the ID and info columns in the VCF input provided to vg. However, after completing the construction process, the ID and info columns in the resulting pan-genome graph were replaced with randomly generated identifiers, and the corresponding genome information couldn't be found. How should we proceed?
