Specify value used to define missing genotypes.

Dear Nick,

I'm wondering that if your XPCLR could deal with missing genotypes?

Previous XPCLR (Chen, et al., 2010.) format the missing genotypes with 9.

I used the same file format to run your XPCLR, and I found that overwhelming majority of SNPs were reported to be multiallelic，possibily due to the missing genotypes?

My genotype file looks like this: 0 0 9 9 1 1 9 9 0 0 0 0 9 9 9 9 9 9 0 0 0 0 9 9 0 0 9 9 0 0 1 1 0 0 0 0 9 9 0 0 9 9 0 0 0 0 0 0 9 9 9 9 0 0 0 0 0 0 0 0 9 9 0 0 0 0 0 0 0 0 9 9 0 0 9 9 0 0 9 9 0 0 0 0 0 0 0 0 0 0 9 9 0 0 9 9 0 0 0 0 0 0 0 0 0 0 9 9 9 9 0 0 9 9 0 0 9 9 0 0 0 0 0 0 0 0 9 9 9 9 0 0 9 9 0 0 0 0 9 9 0 0 9 9 0 0 9 9 0 0 9 9 0 0 0 0 0 0 0 0 9 9 0 0 0 0 9 9 0 0 0 0 9 9 9 9 9 9 9 9 9 9 0 0 0 0 0 0 0 0 0 0 0 0 9 9 0 0 0 0 9 9 0 0 0 0 9 9 9 9 9 9 9 9 0 0 0 0 0 0 0 0 0 0 0 0 0 0 9 9 0 0 0 0 0 0 0 0 1 1 9 9 0 0 9 9 0 0 9 9 1 1 1 1 0 0 0 0 1 1 1 1 9 9 1 1 1 1 0 0 1 1 1 1 9 9 9 9 0 0 0 0 1 1 1 1 1 1 9 9 9 9 1 1 1 1 9 9 1 1 1 1 1 1 1 1 1 1 9 9 9 9 0 0 9 9 0 0 1 1 1 1 0 0 0 0 1 1 1 1 9 9 1 1 1 1 9 9 1 1

Yes. Missing genotypes should be encoded as -1, following the convention of VCF.

[JunpengShi]

Thanks Nick. It works now!

[hardingnj]

Leaving this open as a note to document this more fully. Generally I want to encourage users to give VCF or zarr as inputs though.

dear hardingnj,when i runing the xpclr ,the wrong information to me :ValueError: arange: cannot compute length,how can i deal with this wrong.
