The design data panel allows you to choose the kind of experiment you want to perform. You can choose between three kinds of experimental design:

• Two group comparison: The comparison is performed between the two groups described in the experimental design file. The experimental design file must include two columns: the first one with the names of the samples, the second one with the class to which each sample belongs.

• Correlation with continuous variable: A correlation is performed between the values of each path along the samples and the continuous variable introduced. The experimental design file must include two columns: the first one with the names of the samples, the second one with the value of the variable for each one of the samples.
