Hi All.

I'm trying to use BEAGLE4 to do an IBD analysis. My files are in PLINK format, thus I used PLINK (v1.9) to generate the VCF file (with the --recode vcf flag). Unfortunately I have duplicated markers in the same position (as pointed out by a Beagle exception).

According to the PLINK documentation I could use the flag --list-duplicate-vars to identify and then remove them (with the flag --exclude), but when I run it PLINK with the following command:

$ plink --file myfile --list-duplicate-vars ids-only

it returns:

Error: Unrecognized flag ('--list-duplicate-vars')

Does anyone has any suggestions?

Thanks in advance for your help,

Alessia
