Thank you Martin.
I finally have imported the file but now I've faced another problem.
When I import minutal meteorological data and I try to simulate it minutely, I get the following error: "Error (MinuteSplitter: Input data and clear sky data are not sync.)
I've tried importing the meteo data hourly (to simulate minutely) but I get the same message.
I attach the meteorological data.
Regards,
Endika.
