Inspect Electrical Series Data using AqNWB

This is a simple C++ demo project that shows how to read and analyze NWB (Neurodata Without Borders) files using the AqNWB library. The demo reads a NWB file and performs basic statistical analysis on the ElectricalSeries electrophysiology data.

Integrating LabMetaData Extension with AqNWB

This demo app shows how we can implement and use an extension to NWB via AqNWB. Specifically, this example shows how we can:

1. Create C++ header files for extension schema
2. Integrate extension schema with AqNWB (incl. automatic caching of the schema on write)
3. Implement RegisteredType classes to represent the new neurodata_types defined in the extension
4. Use the extension for writing and reading data

Remote Read Benchmark

This demo project benchmarks the performance of reading NWB data from Amazon S3 using the HDF5 ROS3 VFD or remfile-cpp. It measures the time taken for opening the file, initializing the NWB file structure, locating objects, and reading specific data slices.
