Why Tree sequences generated from Relate (convert .mut/.anc) has no population labels

[itsmestewart]

I have generated a tree sequence using .mut/.anc generated by Relate.

When loaded using tskit.load, the resulting tree sequence has no population labels.
What could be the reason for this?

Note: The original input files have population labels.
Many thank for your assistance.

Hi @itsmestewart, welcome 👋

I think this is a question for the Relate developers rather than tskit, as it (Relate) performs the format conversion. I don't know the details of how Relate does this.

hello @jeromekelleher ,thanks

Yes, this is an isssue with Relate package, I did not get a active platform like this to adress this. I appreciate your response.

Answer from @nspope on same question elsewhere:

Yup -- looks like Relate's converter tool just doesn't construct the individual / population tables. There's no reason why it shouldn't do this (it'd only require parsing an additional input file; there's even a placeholder in the code for it). Would definitely be worth adding this feature (but that's on the Relate side of things, not tskit).
