Olá
I think if I open the file directly on Gretl it may be the best option.
My doubt is that Gretl doesn't read some part of the data because it's already in
the file and when preparing the forecasting model, I must enter new information in empty
cells in order that the programme processes the new information and not the one that was
already in the file (that was opened directly).
I will try it both ways (open it directly and the CSV file) to see if it works.
My Gretl is in Portuguese.
Thank you for your help.
