No subjects found / "No valid datatype present"

[dmhohmann]

Dear Rob,

✔️ UPDATE: I just tried it on linux and it worked. 🐧🪄
❔ Still, do you know about any windows path problems and how to solve them?

may I ask for your help? It must be some simple twitch that I'm missing.

Apparently, the sourcedata2bids image can't find my subject folders, i. e. returns an empty subject list []. Also, when I try to give the extra argument --subject-label 01, it can't find the respective nirs folder (FileNotFoundError: [Errno 2] No such file or directory: '/bids_dataset/sourcedata/sub-01/nirs').

This is odd, as I'm pretty sure my sourcedata is structured in a "bids-comprehensible" way. I also tried e. g. having subfolders in the nirs folders, but it doesn't change a thing. Do you have any ideas? Could it be a mapping problem in docker? (I'm using Win10 and Docker Quickstart Terminal.)

My sourcedata and docker errors are attached. Thank you in advance!

Best,
Dani

Hi @dmhohmann,
Thanks for taking the time to report this. I have a few sneaking suspicions about what might be happening here. I have access to a Windows machine, so I will test it over the next few days and get back to you.

I am also glad you found a work around by using Linux. But lets try and fix the problem still :)

Thanks for looking after this! I guess it was just another hint at me that linux is the way to go 😝

There's two more things I've noticed upon following the fnirs apps tutorial (http://fnirs-apps.org/tutorial/) so far:

• The bids validator is not available any more under the given link (bids.robertluke.net:3000)
• The MNE-NIRS documentation link in your https://github.com/rob-luke/fnirs-apps-scalp-coupling-index repo (title: arguments) is broken. It's now "stable" instead of "main" in the url: https://mne.tools/mne-nirs/stable/generated/mne.preprocessing.nirs.scalp_coupling_index.html#mne.preprocessing.nirs.scalp_coupling_index
