nlgreyobjects in Simulink parameter estimation tool

Hello Experts,

I have used none linear grey box identification object and nlgreyest function for model parameter identification (everything works perfect in command prompt interface). However, I cannot access model parameter values to select them as parameters to estimate in Simulink tool.

I have a trained neural network that estimate parameters from measurement data and need to update model.Parameters.Value(n,m) during simulation time (runtime).

Any help would be greatly apricated.
