bcftools error: bcftools could not parse pval threshold loidly

Question

[mut.patricia]

Hi, I want to call variants with bcftools mpileup + call for human Y chromosome, but I got the error "Could not parse: --pval-threshold loidy" The code I am using:

bcftools mpileup -f refY.fa -d 2000 -q 30 file.bam | bcftools call -m -V indels -ploidy 1 -Ov -o calls.vcf

It generates a vcf file with variants though. Does what does anyone know what the error means? Did not find it googling.

Thanks! Patricia
