Lesson #1: The Structure of NWB Datasets#
NWB datasets can be found in a few different places. Throughout this online textbook, we’ll introduce two primary ways to obtain and work with NWB datasets: through DANDI & PyNWB and through the Allen Institute SDK. In this lesson, we’ll show you how to download a sample dataset via DANDI and navigate the NWB structure.
Learning objectives
By the end of this chapter, you will be able to:
Explain the three common features of datasets: metadata, raw data, and processed data
Identify and implement multiple ways to obtain a NWB dataset via DANDI
Use an interactive widget for a big picture view of a Dandiset
In this lesson, we’ll dig into a couple of NWB datasets that use extracellular recording to simultaneously record from many neurons. First, let’s get the data.
