[Vcftools-help] Help

[Ishaan B. <ish...@gm...>]

Good Afternoon, I am trying to use VCFtools to concatenate 22 vcfs into one
to eventually create one bim file to run pre-imputation checks and impute.
I am attaching a screenshot of the error I am receiving.

Any help would be greatly appreciated.

Cheers.
