Hi! I am trying to do the below but using tped files generated from vcf tools

perform the genome-wide estimatation of IBD sharing:

plink --noweb --bfile nooutliers --genome --out nooutliersIBD

my command was

plink --noweb --tfile chrY.vcf.gz.plinkformat --genome --out chrY.vcf.gz.plinkformat.g

I had this error

Options in effect:
    --noweb
    --tfile chrY.vcf.gz.plinkformat
    --genome
    --out chrY.vcf.gz.plinkformat.g

** For gPLINK compatibility, do not use '.' in --out **
