Issue using tutorial jupyter notebook (localised_spikes_clustered-biocam)

[GrimmSnark]

Hello,

I am trying to play around with herding spikes installed in a conda enviroment alongside spike interface. But when I try and run the first cell of the localised_spikes_clustered-biocam.ipynb file I get the following error:

Downloading data file - around 8GB, so this may take a while, patience...

Any help would be greatly appreciated!

Apologies, this download location is no longer valid. You can now download the file here: https://dandiarchive.org/dandiset/000034/0.211030.0713/files?location=sub-P29-16-05-14-retina02-left It comes in nwb format, so can be read with SpikeInterface. To speed up spike sorting I recommend to convert it into a flat binary first.

Thanks a lot! I will do that now.
