Hi,

Gretl manual states that deseas() calls X-12-ARIMA or TRAMO/SEATS with all options at their default settings.

Two questions:

a) do these 'default settings' change when I change the options interactively in  gretl menus?

b) if not, how can I play with the options? I just want to force log transformation instead of letting it at 'auto' (which I think is the default)

Thanks

Paulo
