+=== Data-analysis import file format ===
+Your data file must be available in form of a table. HeuristicLab does not support sparse matrix formats as used for instance by libSVM. To import your data into HeuristicLab you must prepare your data file to follow a comma separated values format (CSV). On import HeuristicLab tries to guess which separator character is used. Allowed separator characters are ';', ',', 'Space' and 'Tab'. The values should be real-valued format and use a period ('.') as decimal separator. German users can also use the comma (',') character as decimal separator, but of course in this case ',' is not allowed as separator character (use either ';', 'Space' or 'TAB'). The first line of the CSV file can contain variable names.

+Examples for valid HeuristicLab data-analysis files:
+{{{
+x01 x02 x03 y
+1.0 2.0 3.0 0.0
+0.0 1.0 2.0 1.0
