I'm trying to estimate a simple New Keynesian model but get this error message when I try to run the file: 
??? Error using ==> cell.strmatch 
Requires character array or cell array of strings as inputs. 
Error in ==> read_variables at 35 
iv = strmatch(var_names_01(dyn_i_01,,raw(1,,'exact'); 
Error in ==> dynare_estimation at 170 
rawdata = read_variables(options_.datafile,options_.varobs,[],options_.xls_sheet,options_.xls_range); 
Error in ==> flexw at 129 
dynare_estimation(var_list_); 
Error in ==> dynare at 49 
evalin('base',fname) ; 
The estimation part follows mod1a.mod, so I don't understand why the error pops up. 
I'd really appreciate any help--thank you!
