Horses have been considered one of our most prized possessions, used for travel, work, food, and pleasure for at least five and a half millennia17,18,19,20. Nevertheless, the ancestry of various horse breeds and their characteristic traits remains unclear21. In this paper, we describe the patterns and the origins of genetic…

Question about ROH analysis by Plink 1.9

Hi all, I have recently tried to estimate runs of homozygosity (ROH) from my vcf file by using plink 1.9. I ran following code to generate binary files that plink required: plink –vcf myfile.vcf –make-bed –out out_name –no-sex –no-parents –no-fid –no-pheno –allow-extra-chr This vcf file only contains one individual and…
