ndx-ibl-metadata 0.2.0

IBL sessions specific metadata

ndx-ibl-metadata extension for nwbn

This extension provides a way to store various IBL specific metadata for their mice experiments. Metadata about: Neuropixels probe, sessions data and mouse data can be stored in an NWB file using this extension.

Python specific installation:

pip install ndx-ibl-metadata
pip install ibllib

Python usage:

Using ONE API Use the ONE documentation to learn about ONE specific search keywords to retrieve and EID of interest. Then retrieve the info and populate like shown below. Alternatively, you can can also create a dictionary by manually entering correct data.

#retrieve sessions data:
