Read-only matlab files of Dynare 4.4.3 for Mac

[maylily01]

I use Dynare 4.4.3 for Mac OS X. As I want to do IRFs to 1% shocks, I need to
put "options_.relative_irf=1;" before the estimation, then modify a line in
the file: dynare/4.4.3/Matlab/PosteriorIRF_core1.m, but this file is read only,
and doesn't allow me to make the change. However, my co-author, who is
using Dynare 4.4.3 for Windows does not have this problem.

Can anyone have any idea how to resolve this issue? Many thanks!

You have several options:

Option 1

• Download the source code from here: https://github.com/DynareTeam/dynare/bl ... RF_core1.m
• Make the changes you want and drop it in /Applications/Dynare/4.4.3/matlab

Option 2

• Open Terminal (/Applications/Utilities/Terminal)
• Type:

  Code: Select all

  chmod a+w /Applications/Dynare/4.4.3/matlab/PosteriorIRF_core1.m

• Then edit it as usual

In any event, it would be helpful to me if you:

• Open Terminal (/Applications/Utilities/Terminal)
• Type:

  Code: Select all

  ls -la /Applications/Dynare/4.4.3/matlab/PosteriorIRF_core1.m

• Send me the output
