Hello Ricardo Thanks for your feedback but the problem is that mapset cannot be used as input. Because I got this error: p=grass.mlist_grouped ('rast', pattern=pattern, mapset='PERMANENT') TypeError: mlist_grouped() got an unexpected keyword argument 'mapset'. If I avoid using mapset I get a dictionary variable in which, each entry is the list of rasters for each MAPSET.
Am I doing something wrong?
