 fails if there is only one category map.

 ------------------------------------------
 The proposed solution is


 if categorymaps.strip() == '':
         categorymaps = None
     else:
         try:
             categorymaps = [int(i.strip()) for i in
 categorymaps.split(',')]
             # negatiivse ja maplist, _ = maps_from_group(group) suurima
 indeksi kontroll, dublikaatide kontroll (unique)
             nCategories = len(maps_from_group(group)[0])
             if min(categorymaps) < 0:
                 gscript.fatal('Category map index can not be negative.')
             if max(categorymaps) > nCategories - 1:
                 gscript.fatal('Category map index input can not exceed ' +
 str(nCategories - 1))
             if not len(np.unique(categorymaps)) == len(categorymaps):
                 gscript.fatal('Duplicate indices in category map index
 list.')
         except:
             gscript.fatal('Error in category map list input.')

     if ',' in indexes:
         indexes = [int(i) for i in indexes.split(',')]
     else:
         indexes = int(indexes)
     if indexes == -1: indexes = None
