Postestimation Command for Bayesian DSGE model

Good day dynare team.

I am estimation a Bayesian DSGE model using dynare 4.5.3.

I need the postestimation commands to retrieve simulated correlations, moments and the RMSEs from the results.mat.

I would really need someone to help me on this please.

Thank you so much
