updating notebooks

[djarecka]

@bendichter - I'm thinking about updating the notebooks from this repo, but I wonder if your yesterday notebooks were not related to this repo

[bendichter]

I just made that on my own, but we could add it to this repo! Eventually. It's a bit messy right now.

[djarecka]

So does it make sense to update NWBWidget-demo.ipynb and 000004_demo_analysis.ipynb (they are failing in the current form), or you have a different idea for the content in this repo.

[satra]

it would be good to update them and perhaps use the nwbstreaming environment directly to pull in the streaming data.

[bendichter]

I can work on this

[bendichter]

@satra what do you think of this?

https://github.com/dandi/example-notebooks/blob/master/NWBWidget-demo.ipynb

[satra]

thanks that looks nice. regarding the search paths, there is a dedicated endpoint for that:

https://dandi.readme.io/reference#dandisets_versions_assets_paths_read

that specific api return will change shortly (dandi/dandi-archive#312), but that's what you should use instead of the current formulation.

[bendichter]

@satra I'd like to be able to demonstrate API best practices but I don't understand how to use this. What I need is an API where I can input the dandiset identifier and the nwb file path and have it output the asset_id of that NWB file. Is that possible with the API?

[satra]

yes that api has exactly those things but will return a list of objects. path is a parameter to that api endpoint. if you fill in the values in readme.io it will show you the corresponding python code.

[bendichter]

@satra

I've been playing around with it and this is the closest I've gotten

but this neither returns the single object I am looking for nor returns the asset ID. Also, the documentations says:

The specified path must be a folder; it either must end in a slash or (to refer to the root folder) must be the empty string.

but I want to specify the path of a file.

[satra]

really sorry, i gave the wrong api endpoint.

import requests

url = "https://api.dandiarchive.org/api/dandisets/000053/versions/draft/assets/"

querystring = {"path":"sub-npI1"}

headers = {"Accept": "application/json"}

response = requests.request("GET", url, headers=headers, params=querystring)

print(response.text)

[satra]

and you should be able to give the fullpath. the other endpoint returns the list of objects at a given level in the hierarchy

[bendichter]

that works, thanks @satra
