Tesfalidet,

I am not farmiliar with the DSSAT model but i guess your error may be due to an 

input error for a real value. You probably have an input value which does not have 

dot (decimal point) after a numerical value.  The program may be reading this as 

an integer rather than a real value if the dot is non-existent. Check again & 

ensure all your nunerical inputs that are supposed to be real values have a decimal point.

Hope this helps.

Dear Listers,

After carefully creating the soil, weather, and experimental details
file, I tried to run the DSSAT v3.5 model. But I got the following
message:

Runtime error F6103: Read <IBSNAT35.INP> - invalid real.

DSSAT v3 vol 2 user's manual gives examples of general error messages
but not runtime error messages. Does anyone know what this runtime error
means?

Thanking you in advance.
