Note potential problems if DynareOBC is on Google Drive or similar

Hi,
I'm trying to run the the example from the Iacoviello-Guerrieri model but I keep getting the following error:
Error using copyfile
No matching files were found.

Error in dynareOBCCore (line 181)
copyfile( SteadyState2MFileName, 'dynareOBCTemp2_steadystate2.m', 'f' );

Error in dynareOBCSetup (line 297)
dynareOBC_ = dynareOBCCore( InputFileName, basevarargin, dynareOBC_, @()
EnforceRequirementsAndGeneratePath( Update, OriginalPath, CurrentFolder, dynareOBCPath,
InputFileName, varargin{:} ) );

Error in dynareOBC (line 711)
dynareOBCSetup( OriginalPath, CurrentFolder, dynareOBCPath, InputFileName, varargin{:} );

Error in ReplicateFigure3 (line 1)
dynareOBC GI2017.mod ShockSequenceFile=ShockSequenceP.mat MLVSimulationMode=1

Error in RunExample (line 11)
ReplicateFigure3;

I followed the installation instructions so I don't think this error is coming from that. I'd greatly appreciate your help with resolving this issue.

What version of Dynare are you using? DynareOBC works better with Dynare 4.5.x.
What happens when you run "dynare GI2017".

[dedav514]

Thanks for your prompt reply Tom. I'm using Dynare 4.5.7. When I run "dynare GI2017, I get:
**There are 16 eigenvalue(s) larger than 1 in modulus
for 16 forward-looking variable(s)

The rank condition is verified.

Error using varlist_indices (line 62)
The following symbols are not endogenous variables: irf1 irf2 irf3 irf4

Error in GI2017 (line 503)

When I run dynareOBC GI2017, I get:
**There are 16 eigenvalue(s) larger than 1 in modulus

The final message makes it clear that DynareOBC is not fully installed. Do you have admin rights on that machine? Have you installed Gurobi or similar?

[dedav514]

Thanks Tom. I do have admin rights as well as Gurobi installed. What likely caused the problem was the fact that I placed dynareOBC in my google drive folder instead of a local one (as explicitly pointed out in the instructions). I corrected for this and it works fine now. My apologies for missing this and bothering you with what turned out to be a very straightforward issue.

Good to know you've fixed it. I should note potential problems with Google Drive.
