Hi there,

I’m currently working on some wrapper scripts around the AllenSDK for our lab’s software. I’m looking to incorporate some testing files into our repo, but unfortunately the smallest Neuropixels session is 1.7GB.

I was wondering if your team had a smaller sample session that could be used for testing purposes.

Thank you!  
Selen

Hi Selen – We don’t have any smaller files available currently. I suppose the contents of such a file would depend on what you need to test. I would recommend exporting a truncated version of one of the original NWB files by using the [`NWBHDF5IO`](https://pynwb.readthedocs.io/en/stable/export.html#exporting-nwb-files) class from the `pynwb` library.
