Re: Looping over file names

Post by Archiver » 4 years ago


The input and output via excel is working for one instance if I don't use %instance% and call gams via run.gms. I just don't understand how to run gams from another gams file and add a number or text via %instance% like here in the example.

The excel data has no data information.

You don't have to run the model for me, I just want to understand the line the trick with %instance%

Hi Renger,



attached you will find my code.

I want to run this model with several input files and create several output files.



The input is described in EXCEL and should be read from one sheet: line 10 for instance = 1 and from line 20 for instance = 2 and so on.



The same should happen for the Output. It should be written to one sheet: line 10 for instance = 1 and to line 20 for instance = 2 and so on.





I want to work with "run.gms" and "makerun.gms" files like described here.

RE: Looping over file names

Post by Archiver » 4 years ago


HI Alex



The trick with %instance% is that Gams replaces %instance% in your code with the value of instance in the call ($call gams mymodel –instance=1), which works fine if I look at the output.



If you want to test your model you could add



$if not setglobal instance $set instance 1



to the model_03.gms-file. Then you could test the model, running model_03.gms directly without run.gms.



As you said, the excel file does not contain data, so I can’t check what is going on. If you want, I can check if you send me at least the gdx files (they shouldn’t be that big) for your test model.



Cheers

Re: Looping over file names

Post by Archiver » 4 years ago


Hi Renger,

thank you.

I know that the input gdx file is created but the model will not be solved and the (output) excel file is not changed. Do I have to type "execute" instead of "call"?

I sent you a working gams and excel file for one instance without the %instance% and run.gms file.

You don't need the gdx file. The excel file is containing data now.

Re: Looping over file names

Post by Archiver » 4 years ago


You just need the "Model_05.gms" and "RunTest_2D_1.XLS" in one folder and it should work with reading and also writing to excel

Hi Renger,

thank you.

I know that the input gdx file is created but the model will not be solved and the (output) excel file is not changed. Do I have to type "execute" instead of "call"?

I sent you a working gams and excel file for one instance without the %instance% and run.gms file.

Hi Alex



Runs fine on my computer. Here the output in my dos window.

What might happen is that you have the excel file open (see in the gdxutils.pdf for closing it using XLStalk.exe).

I deleted the results in the excel file and when I run the model, the sheet is filled with data. I adjusted the file bringing back “instance” and it also solves fine.

I guess you misunderstood me.
I know that the model is running fine. That was not the issue.

The issue is that my model is not solving if I use the %instance% approach.
Could you maybe send me the adjusted file back?
