Hola Ernesto, Can you send us your error messages? I suspect that you are using expliocit filenames in your .mod or the command file. You do not need to include a data stub.mod statement in your stub.mod file. We rename the files that are submitted, so you cannot use explicit filenames; the server wil load data and model file for you. Kind regards, Sven On Mon, 24 Nov 2008, Ernesto Staffetti wrote:

Dear Sirs,

we are trying to use the NEOS SERVER with Minos, Ipopt, with AMPL. We use two files (a ***.mod and a ***.dat file).

After uploading both we get an error. The server does not find the ***.dat file.

Could you please help us in solving the problem?

Thanks in advance and regards,

Ernesto Staffetti
