Dear members, I am using DSSAT35 for simulating sowing dates effects on some chosen maize varieties in the southern region of Togo (West Africa). But whenever I run the simulations, the output file stops at the header SIMULATED CROP AND SOIL STATUS AT MAIN DEVELOPMENT STAGES giving the maturity details with the following message below them: File not found. Create input file. File: VOGA0201.WTH Line: 1 Error key: IPWTH VOGA0101.WTH (and not VOGA0201.WTH) is my weather file but when I tried to rename VOGA0101.WTH to VOGA0201.WTH, the message would appear again asking for, this time, VOGA0301.WTH and so on. Can you help please?
