**2.** I would like to perform quantitative association testing for all traits. 
I have been fighting all day and cant find an answer anymore, why I am getting an error (see below), when running this command line: 

    $ plink2 --assoc --bfile binary_fileset --pheno outputfile.txt --pheno-name Caffeine -pfilter 1e-5

**Error:** 

    4096 MB RAM detected; reserving 2048 MB for main workspace.

    1008 people (0 males, 0 females, 1008 ambiguous) loaded from .fam.
    Ambiguous sex IDs written to plink.nosex .
    0 phenotype values present after --pheno.

Hi mmukhame321, 
    I guess you have solved this problem. It took me a while to find out why. My .fam file does not include the gender information, so there will be a warning like "If you don't want **those phenotypes to be ignored**, use the --allow-no-sex flag". I suppose that's why it came out to the "Note:  No phenotypes present." After I added the flag "--allow-no-sex", it worked.  Hope this information could help others who are disturbed by this annoying problem.
