  1. Hello, I tried to import the measured weather data using ASCII import on PVsyst 6.49 . I selected the columns with Year, Month, Day and Hour for the time stamp, and I selected columns with POA and ambient temperature and specified tilt and azimuth. But I could not convert the file (Start Conversion button is gray), the warning message is: The Import Ascii tool requires the Global Horizontal, Diffuse Horizontal, and Temperature to be defined each month. Please generate a full set of data before going-on (for instance with MeteoNorm). I did this conversion successfully in 6.35. I don't know if I need to change some settings to make it work in 6.49. Could you help me troubleshoot? Thanks!
