Hi Theodosia, When no samples are found, usually this is due to one of these issues :
- the image and the reference data files do not have the same projection - the reference data has to be made of polygons (not points, not poly-lines) - the attribute of the vector data containing the class label (integer) has to have the same name as the one you specify with the -sample.vfn option in the application If you do not manage to solve your problem with these hints, you may want to make available a small data set showing the problem so we can investigate.
