I am trying to download ephys traces from DANDI (Gouwens et al. 2020), as indicated in this example. However, when I type !dandi download https://girder.dandiarchive.org/api/v1/item/5edb30e22dace54b6f9b4051/download I get the following error Error: HTTPSConnectionPool(host='girder.dandiarchive.org', port=443): Max retries exceeded with url: /api/v1/item/5edb30e22dace54b6f9b4051/download (Caused by NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x7ffad6887250>: Failed to establish a new connection: [Errno -2] Name or service not known')). On the other hand I can download some other files from DANDI, as indicated in DANDI examples, so I don’t think that there is a problem with DANDI per se. Could you please suggest how I can get access to the files from Gouwens et al. 2020?
The DANDI archive changed the backend system that they use to serve files.
The easiest option for you may be just to download the whole set using: dandi download DANDI:000020/0.210913.1639
For specific files, you may choose to get a single-file download link by browsing for the experiment of interest in this interface: DANDI Archive
For a single file, you can get the correct URL from that site and then download with: dandi download https://api.dandiarchive.org/api/assets/cc720736-2f21-415b-b7d2-bf49f1dbc5da/download/
I will need to update that file manifest with new links soon.
