[BUG] Can't download Datalad datasets

[seanhatton]

Is there an existing issue for this?

• I have searched the existing issues

Expected Behavior

I am using the web-based query tool to select some datasets: some from Datalad and some from github. Using the Neurobagel DATAGET service I want to download the raw data and associated metadata (e.g. participant.tsv).

Current Behavior

Using Neurobagel DATAGET I can download the github study files but not the Datalad studies. It gets the folder structure but no files. Opening the dataset-level-results.tsv, browsing the PortalURI for a Datalad dataset (e.g. https://datasets.datalad.org/abide/RawDataBIDS/CMU_b) shows directory structure but no files (e.g. participants.tsv, NIFTIs). Browsing Datalad.org the files are there.

Error message

All files have a red cross on the icon. With a Datalad dataset, when you click to open (e.g. participants.tsv) it says the file cannot open because the link is broken. With OpenNeuro the participants.tsv is downloaded and accessible.

Environment

• OS: Ubuntu 24.04
• Python version: 3.9

How to reproduce

In the query tool select a dataset "from International Neuroimaging Data-sharing Initiative" then use the DATAGET function to clone the files down. Open the downloaded content and see if the files at the root of the dataset directory structure are downloaded or a broken link.

Anything else?
