New Post: Fatal Error : Expected phenotype indicator in file [allF2phe_plink.txt] near line 1:8 to be 0, 1, -9, or a floating point number.

I am trying to use FaST-LMM the very first time, but I'm getting a following error, and I'm wondering whether the problem derives from wrong coding, or something else:

Fatal Error : Expected phenotype indicator in file [allF2phe_plink.txt] near line 1:8 to be 0, 1, -9, or a floating point number. Found [foodconversion]

I'm very comfused about the error. It's ok when i performed this command in plink: plink --file cleanF2deChr0 --noweb --pheno allF2phe_plink.txt --mpheno 4 --epistasis --out test

Why did the phenotype file used in fastlmmc find error? Can anyone see any obvious errors with this code and/or files: fastlmmc -verboseOutput -file cleanF2deChr0 -fileSim cleanF2deChr0 -pheno allF2phe_plink.txt -out $savedir/test.dummy.txt
