Erros in Bayesian estimation,could anyboby help me with this?

Hi everyone, when I was doing Bayesian estimation,I got these error messages:

error using dseries/subsref (line 220)
dseries::subsref: Indices are out of bounds! Subsample cannot end after 88Y.

error in makedataset (line 252)
DynareDataset = DynareDataset(FIRSTOBS:lastobs);

error in dynare_estimation_init (line 538)
[dataset_, dataset_info, newdatainterfaceflag] = makedataset(options_,
options_.dsge_var*options_.dsge_varlag, gsa_flag);

error in dynare_estimation_1 (line 116)
dynare_estimation_init(var_list_, dname, [], M_, options_, oo_, estim_params_,
error in dynare_estimation (line 105)

error in Bayesian (line 324)

error in dynare (line 235)
evalin(‘base’,fname) ;

And I do not know how to solve this problem.
Could anyone please tell me how to solve this problem? Thanks a lot!

You most probably specified nobs and first_obs in a wrong way. Without seeing the files it is impossible to tell. (18.3 KB)
Thanks for your answering. Here are the files. Could you please give me more details?
