 ## phenotype (and covariates) file
 
-The phenotype file is a tab-separated values (TSV) file. The first line MUST be a header with column labels. Each row corresponds to one individual. The column labelled `sample-id` contains the sample identifier for that individual. Other columns each contain a phenotypical trait for that individual. The headers of these columns MUST be the names of the phenotypes. Column headers are case-sensitive.
