I use estimation( …, mode_compute= 6,…) to get the mode file ‘mymodel_mode.mat’, then I change to use estimation( …, mode_compute= 0,mode_file=‘mymodel_mode.mat’,…). But there appears a message:

Unrecognized function or variable ‘constant_part’.

Error in store_smoother_results (line 112)

trend_constant_observables=constant_part+Trend;

Error in dynare_estimation_1 (line 559)

[oo_,yf]=store_smoother_results(M_,oo_,options_,bayestopt_,dataset_,dataset_info,atT,innov,measurement_error,updated_variables,ys,trend_coeff,aK,P,PK,decomp,Trend,state_uncertainty);

Error in dynare_estimation (line 105)

evalin(‘base’,[fname ‘.driver’]) ;

So, is it wrong to do this in my way? thank you for help check this issue.
