Pruning algorithm in Dynare 4

Dear All,

I have a problem of explosive stochastic simulations for large shocks using a second order approximation of a medium sized model coded in Dynare 4. It would be nice to try whether the pruning algorithm of Kim, Kim, Schaumburg, Sims (2008) would help me that has been implemented in Dynare 3. ( Pruning algorithm for second order approximation ) Is it implemented in Dynare 4?

Thank you: Peter
