I don’t know how to get past the error message I see when I run the Zika tutorial workflow.
I was able to work it out!
Hi @rania.milleron, I’m glad you were able to resolve your issues! If you are able to, would you be willing to share your approach here? That would help others with the same problem in the future.

@gej would you be able to share a few more details about your setup so that we can see what the problem might be?
- What’s your operating system? Linux/mac/windows
- How are you running the workflow? What’s the exact
nextstraincommand you’re running that results in the problem? - What’s the output of
ls -alhtin your working directory?
I am following the example on this page, Running a pathogen workflow — Nextstrain documentation.
-
Ubuntu 22.04 LTS

I followed the example and use the exact same commands. I was able to clone the repository with “git clone GitHub - nextstrain/zika-tutorial: Data and scripts for Zika virus tutorial”. Error show when I run the workflow.

Hi @gej,
Thanks for the information. It looks like Snakemake is having trouble creating the .snakemake directory, even though your gej user has the proper permissions.
To understand the situation better, can you provide the following details?
- Output of
whoami. - Output of
nextstrain version --verbose. - The host machine of your Ubuntu 22.04 LTS. Examples: a Windows computer using WSL, a remote computer, or a local computer with Ubuntu installed directly.
– Victor
It is a local computer with Ubuntu installed directly.

Hi @gej,
I tried to reproduce your issue using a new instance of AWS EC2 running Ubuntu 22.04, but everything worked fine. The reason for this error isn’t clear to me, and I’ve asked another teammate to take a look.
In the meantime, can you try using the Conda runtime, and let me know if that works?
nextstrain setup --set-default conda
nextstrain build --cpus 1 zika-tutorial/
– Victor
If you could do this, it will be useful for our investigation. First, start a shell in the Docker runtime:
nextstrain shell --docker zika-tutorial/
Then, copy the output of these commands:
ls -alhid
Thanks for your cooperation. Hopefully we can understand this issue soon.
