In many cases, we wish to use the FIS to infer output values for a whole data set, stored in an external file.
To be usable as a data file in FisPro, the file must be in text format, with one line per example, and as many fields as the total number of input variables (active plus inactive) declared in the FIS.
The data file may also include as many supplementary fields as there are output variables.
The field separator is automatically detected. Spaces or tabulations are not valid separators.
Learning menu options are available only if a data file has been opened. All of them need at least one output field to be present in the data file.
