Victor,

One last correction to my first reply.  When plotting predictions
against observed data, the X-axis is Predicted values and the Y-axis is
the Observed values.  I recommended the opposite in my earlier reply,
which was incorrect.

> Hello everyone on the list i am almost newly on DSSAT son hopefully this won´t be a dump question. I m on a run to simulate maize yield and I followed all the route of DSSAT to load experimental data, crop management data, weather data and soil data. I established the simulation options to generate yield but my problem is that when I select the options in "weather" and "models" menu, on the window to select the experiments and simulation outputs, only appears weather.out. So in consequence the results are very unhopeful for me because i cannot see any yield simulation. What could be wrong ? any idea ?  Regards
