Hello everyone, I am doing a GWAS analysis by plink 1.9. When I upload my covariate file, it reads
Ignoring --covar since no commands reference the covariates
I have double-checked my covariate file and it is in the right format (as it works as a phenotype file). I have also checked the value of the covariate file (with R) and it is indeed numeric. Here it is my command:
--bfile ../genotype_all/qc_1 --pheno ../phenotype/weight --covar test_covar.txt --covar-number 1 --assoc
and here it is the log:
Logging to plink.log.
Options in effect:
--assoc
--bfile ../genotype_all/qc_1
--covar test_covar.txt
--covar-number 1
--pheno ../phenotype/weight

488371 people (223470 males, 264803 females, 98 ambiguous) loaded from .fam.
Ambiguous sex IDs written to plink.nosex .
486613 phenotype values present after --pheno.
Using 1 thread (no multithreaded calculations invoked).
Warning: Ignoring --covar since no commands reference the covariates.
Can anyone tell what is wrong? Thank you very much for your help!

Please use the formatting bar (especially the
codeoption) to present your post better. You can use backticks for inline code (`text` becomestext), or select a chunk of text and use the highlighted button to format it as a code block. I've done it for you this time.
