The error says fastlmmc was looking in the file allF2phe_plink.txt for a numeric value and found "foodconversion" in line 1 column 8 , so it sounds like the file is mal-formed.
Do you have a header row in the file allF2phe_plink.txt? If so, are the first two labels FID and IID?
If you don't have a header, then it sounds like you have the text string "foodconversion" where the format is expecting a numeric value.
The file reader does validation of the file as it is read so even though you are saying -mpheno 4, it is still expecting all the columns to be well formed.
What version of plink did you run?
The alternate phenotype file is described in more detail at http://pngu.mgh.harvard.edu/~purcell/plink/data.shtml#pheno
If that is not the problem, could you send allF2phe_plink.txt (or at least the first lines) so we can look it over?
thanks
