No Phenotypes Present’) even with a covar file is present

Hello,

I’m utilizing PLINK –lasso for feature/SNP selection, running the following command:

plink --bfile SNPsFile --allow-no-sex --lasso 0.46 --covar pheno.txt  --covar-number 1-9 --make-bed --out Test

Resulting in the output below:

Even with covars uploaded, I am still getting this issue. Pheno.txt is a tab-delimited .txt file.

Any solutions? Thanks in advance.
