The excel file (.xls or .xlsx) must have the following structure:
- Each row represent a run. You can introduce only the mean or similar, but in that case the statistical tests could not be used
- Each column 'F' (with number as a positive value) is the result for each function to use in the comparison.
- Optionally a column 'alg' with the algorithm name (mandatory for several algorithms).
- All the other columns are used to group results.
