The input of the software simply consists of two data files containing the positive and negative subjects, as defined by the user. It is important to be aware of the definition used for the negative and positive data, since the meaning or interpretation of false positives and true positives reported will depend on this definition. Each input file must have a multi-column format, where a given column contains the obtained scores from a specific classifier for all subjects tested. Additional input parameters that do not affect the results of the calculations are optional and include a job name and the possibility of getting the display of the classifiers sorted by decreasing AUC values, among others. Detailed on-line help about the required format for the input files is provided.
