.VDF optimisation file

Post by salman_psh »

Hi,

I optimized my model parameters. I copied file with data folder. Now when I run the model I get this message
"ERROR: Unable to open the file BASERUN.vdf. "

why is this error message coming while I can see the model out put in graphs. Is the output incorrect if this message comes?
Or this message can be suppressed/ignored as now the model is using optimised values.

Thanks,
Sa

Can you upload anything? It sounds like you've got the baseline.vdf file in a different folder.

Several things could cause that message. If you're restarting from the optimized .vdf, that's a bit fragile. Generally, if you want to do runs starting from your optimized parameters, you should load the .out file from your optimization as a changes file (Model>Simulate>Changes>Load Changes From...).
