Data generated by Dynare

I am using Dynare for the first time, trying to run an RBC model using stoch_simul. However, I am having trouble identifying the data used by Dynare to calculate the moments of the simulated variables.

One of the variables I have tried to simulate for example is y, when I try to calculate the moments of the simulated variables manually using MatLab functions ( std(y), mean(y)…), I get different numbers from Dynare’s output.

Can anyone explain to me why?

The data will be in oo_.endo_simul and moment computation will drop the first options_.drop periods.

The inconsistency was due to the options_.drop, thanks a lot for your help.
