Use frequency 5, 6 or 7 depending on whether the data are working-day, all days apart from Sunday, or full 7-days per week. We can maybe handle weekly data in databases (though not yet), but I think that would have to by start-of-week date in ISO 8601. There's no facility at all in libgretl for handing something like "2017:40". Allin
