reference panel with missing genotypes #12

Open mfz opened 5 years ago

mfz commented 5 years ago

Good day!

Thank you for making Minimac available!

I am trying to convert a reference panel to M3VCF format using

Minimac3 --refHaps refpanel.vcf.gz --processReference --prefix ReferencePanel

but I get an error message "Missing Value for Individual: xxx at Marker: xxxxx"

Looking at the vcf file, the genotype in question is '.|0'

Is there any way to allow missing genotypes? Or can Minimac directly impute them?

If I use a small version of the VCF file with only a few markers the program finishes successfully.

The version of minimac I am using is f142810

Best regards, Florian

m3vcf file is for the reference panel. The reference panel cannot have any missing values, hence you are getting the error.
