I used the following command on the vcf file to calculate roh. My question is how can I have this plot?

bcftools roh -G30 --AF-dflt 0.4 file.vcf

Hi mohammadhassanj,

I don't know exactly the format of the files produced by this command, but if you can use R, I'm pretty sure you can plot them using karyoploteR and maybe with the help of CopyNumberPlots to easily get the variant allele frequencies from the VCF. You can check the karyoploteR tutorial to find some more information and examples.

Hi bernatgel

thanks for reply

According to the command, a file is generated in above format in which the roh is estimated, but I do not know how to calculate "heterozygosity as dosag". Thank you

Heys, what I did is to filter out the RG observations from the first column and then plot them along the genome with R. I did not manage to obtain this plot.
