Half-siblings are treated as full siblings

[oleraj]

I noticed that in a pedigree I analyzed where two individuals are half-siblings (same mother), they were classified as sib-sib (0.50), but they cluster with the individuals who are uncle/aunt-niece (0.25). I think half-siblings can be classified as 0.25 so they will cluster properly. See AI001905 and his half-siblings AI001903 and AI001904 in the attached files.

Thanks.

I'll look into this. Meanwhile, can you give 1905 a fake parent? I think that will give you 0.25 based on the current logic.

Sure I can do that, thanks.

your issue aside (but not forgotten) I love seeing peddy use like this!

It's a great little tool, thanks for providing this to the community!

bumping this as a reminder to myself. this would be good to resolve.

Thanks, happy to test once you have a fix in place.
