This workflow estimates kinship and IBD sharing probabilities between all pairs of
samples using the PC-Relate method, which accounts for population structure by
conditioning on ancestry PCs.
Recommended usage is to provide the pruned GDS file from the LD pruning workflow as input.
Additional variant filtering may be done by providing a file of variant.id to include.
Note that the variant ids in the LD pruned GDS file may be different than the ids in the
per-chromosome GDS files used as input
