* ANT file missing error

[vsaini]

What are the reasons for *ANT File missing error while running a model? any possible solutions?

* Its only happening in one model while rest of the models are working fine.

Likely the solver has failed to find an optimal solution in that case. Or it could also be some GAMS error. In any case, looking at the listing file (*.lst) should reveal the cause, and possible approach for cure. Maybe you can post it (zipped)?

If there is no LST file then your GAMS system path has not been properly established.

Dear Dr Antti and Dr Gary,

Thank you for your response. I checked for the LST file and from there I got a clue to check for the QC file. Finally, I get a hold on the problem. The issues occurred due to addition of unnecessary time slices by AnswerTIMES (this sometimes happens when we use the excel import feature) in one of the country model. I remember this happening sometimes back too when I used the excel import feature but it slipped my mind. 

Well now the model is working fine.

Once again, thank you for your quick response.

Regards

PS. To resolve this issue I just have to remove the redundant time slices from my model and it worked fine.
