When I run pc_relate on my data set I get negative IBD1 and IBD2 values. To my understanding IBD1 and IBD2 denotes the probability for two individuals of sharing 1 or 2 alleles at a locus, respectively.

Since probabilities should be in [0, 1] I find it difficult to interpret the negative results.

I run on whole exome data with maf > 0.05 and output all pairs.

Can I simply threshold all IBD1<0 and IBD2<0 to 0?
