Hello!

I am new to Matlab and I have a simple question with respect to the BEAR toolbox by the ECB. I use Windows.

BEAR runs for me with the default data file with a Bayesian panel VAR with dynamic structure factor. But if I try to insert my own data in the exact same excel file in accordance with the instructions in the BEAR User Guide, it gives me an error message. I just added three excel sheets in the input excel file in the default folder of BEAR, so all I cahnged compared to the default case is that I added the three sheets.

I made sure that they are in exactly the same format as the default data sheets and that there are no missing values or errors.

I adjusted all specifications in MATLAB for the Bayesian panel VAR with dynamic structure factor to the new data e.g., new dates, endogeneous variables, etc.

I still get the following error message which seems to refer to the data format:

Index in position 1 is invalid. Array indices must be positive integers or logical values.

Error in bear.gensamplepan (line 392)

temp=[temp data(Fstartlocation-lags:Fstartlocation-1,endolocation(jj,1),ii)];

Error in BEARmain (line 387)

=bear.gensamplepan(startdate,enddate,Units,opts.panel,Fstartdate,Fenddate,Fendsmpl,endo,exo,frequency,lags,F,CF,pref,opts.ar,0,0, n);

I did not provide the code because I am using the BEAR app interface. If it could help to include the code, I can also look for it.

Thank you for any help you can provide!
