Hi,

Phenotype data file should explain the variables in your samples. Ideally it should either have a "condition" or other variable like "time point" depending on the design of your experiment. If you look at csv file from the data, it is clear that the first column consists of sample name/ID, second column is a variable. Can you explain your experiment design?
