Dear Community,

I am running the simulation at different offset values through test manager. I would like to plot vehicle speed vs these offset values in MATLAB. but I don’t think these values are being recorded in erg file. How can I do this?

Thanks

Hi Prabanjan,

they are recorded. See the corresponding .erg.info file.

> NamedValues.Count = 1  
> NamedValues.0.Name = Long\_Offset  
> NamedValues.0.Value = 1000

How can I read the erg.info file?
