Downloaded the code associated with Touboul & Brette 2008 from modeldb.science/114242. Installed the docker image for brian1.4.3 as described at [Container image for Brian 1 — Brian 2 2.5.4 documentation](https://brian2.readthedocs.io/en/stable/introduction/brian1_to_2/container.html#container-image-for-brian-1). Then tried

podman run -v “$(pwd):/workdir” brian1 python behaviors.py

and of course got this msg

python: can’t open file ‘behaviors.py’: [Errno 13] Permission denied

so tried this instead

podman run -u (id -u):(id -g) -v “$(pwd):/workdir” brian1 python behaviors.py

(sorry, haven’t figured out how the “preformatted text” markup is supposed to work, so a couple of dollar signs aren’t showing in that line) and got the same msg. This under Rocky linux 9.3 (RHEL semiclone) with latest updates. What next?

Hi @xnm. I’m afraid I cannot reproduce this on my machine, i.e.:

```auto
podman pull docker.io/briansimulator/brian1.4.3
podman tag briansimulator/brian1.4.3 brian1
podman run -v "$(pwd):/workdir" brian1 python behaviors.py

```

runs without a permission error. It raises an exception about the access `optimize`, but this is fixed by adding `from scipy import optimize` to the script. The permission issue we mention in the documentation is with respect to files _written_ by the script – this does not apply here. I don’t have experience with RHEL/Rocky Linux, but this problem does not seem to be related to the Brian 1 container itself but rather to your local environment (how/where you downloaded the files, the `podman` version you are using, etc.).

All that said, if you are interested in the results of Toubul & Brette 2008, you can also use the Brian 2 version of their code, included as an example in the Brian dicumentation: [Example: Touboul\_Brette\_2008 — Brian 2 2.5.4 documentation](https://brian2.readthedocs.io/en/stable/examples/frompapers.Touboul_Brette_2008.html)

Hope that helps!  
Marcel

PS:

> sorry, haven’t figured out how the “preformatted text” markup is supposed to work

Pre-formatted text uses markdown syntax, i.e. either enclose text in ``single backticks`` for in-inline formatting, or in

````auto
```
triple backticks
```

````

For multi-line (e.g. code snippets).

Thanks for the prompt and very helpful reply, Marcel!

Touboul & Brette 2008 is a very nice nonlinear dynamical system analysis. But I was looking for something much simpler–in particular, something that corresponds to Naud et al. 2008. And sure enough, there it is in the Brian documentation!
