Your question is not very clear to me. But if bothers on statistical packages for analysis, I am sorry i wouldn't be able to help. I am not conversant with the package you are using.
I am agree with my colleague Testo Richard Silungwe... Alternatively you can the proper input files or syntax errors.. Otherwise if all the procedures are followed systematically there is no chance of not giving output ...
If you are still unable to get your desired file, you should re-install the DSSAT package having original key. You can freely download it from the DSSAT website ( https://apps.agapps.org/ide/serial/index.php/request?sft=3 ) after registration.
Dear Anshuman Gunawat I would like to advise to please re-intall the DSSAT Module along with original key. As per suggestion given by Dr Sudhir Kumar Mishra that is right procedure to get the desired results as per the simulated values.
Basically, you have to check the values which you have fill in programme, sometime by mistaken any value not fill properly it need to be observed critically.and also the same set of treaatmnt you have to run in other few models to check the confirmity.
