Hi,

I'm running the following command to find runs of homozygosity:

plink --bfile path/G02 --homozyg --out path/G02 --allow-no-sex

I get this log:

Run defined as: 
Homozygous segment criteria:
  length (kb)       = 1000
  # SNPs (N)        = 100

Writing segment summary to [ path/G02.hom.summary ]

I get nothing in the homo files except the headings. Anyone has any idea on why this is?

Thanks!
