parameter estimation of vibration model

I am trying to do parameter estimation for a Simulink model of a triplex mud Pump. In that, there is three simulation output which includes flow, pressure, and vibration. I want to do parameter estimation for the vibration output with real-time vibration-measured values. When I tried to do this with the parameter estimation app it is not taking Simulink vibration output to compare with measured values. why it is not taking scope output of vibration?

i think u need to enable "log data to workspace" and "structure with time" in output scope
