I am attempting to use the BVAR_DSGE routines on the Lubik-Schorfheide EU model published in Schorfheide's site under "nber-ma2005-public.zip\projects\Active\nber\public\dynare\euro_m1\euro_m1-mod".
The model runs perfectly under normal estimation. Unfortunately, when attempting BVAR-DSGE estimation, despite many attempts changing various estimation options, it is impossible to get beyond the standard Bayesian estimation of the parameters, viz:

I am unable to comprehend why there is reported the error "Error using ==> mtimes Inner matrix dimensions must agree"

Would Stéphane be able to help with this?

Dear John, I was not able to run your file... The problem here is that you have more shocks than observed variables. The identification scheme proposed by Del Negro and Schorfheide requires that the number of structural innovations equals the number of observed variables in the VAR model.

Best, Stéphane.

Dear Stéphane,

Many thanks for your kind reply and apologies for this late response - I have been away.
Apologies also for having forgotten to include the mode_file with my submission; this is why you could not run my programme.
But in any case, you are quite right that the problem lay with the number of shocks permitted under the DelN_S identification scheme. Thank you for pointing this out.
Best regards

Hello again Stéphane. I have sorted out the earlier problem, thanks to your note about the identification problem, but now have another problem with a different model.
As you can see from the error messages below, this case is not supposed to happen and I am asked to contact you. Hence this. Any thoughts?

This case shouldn't happen. Contact the authors of Dynare
