AqNWB is a C++ API for acquiring neurophysiological data directly into the NWB (Neurodata Without Borders) format. Our goal is to provide a lightweight API to integrate with existing acquisition systems.

Please note, AqNWB is currently under development and should not yet be used in practice.

Below is a high-level overview of the project structure and capabilities we are targeting:

• A C++17-compliant compiler
• CMake >= 3.15
• HDF5
• Boost
• Doxygen (optional, documentation building is skipped if missing)

Here are the steps for building in release mode with a multi-configuration generator:

cmake -S . -B build
cmake --build build --config Release

Note, if you are using custom installs of HDF5 or BOOST that are not being detected automatically by cmake, you can specify HDF5_ROOT and BOOST_ROOT environment variables to point to install directories of HDF5 and BOOST respectively.

Here is the command for installing the release mode artifacts with a multi-configuration generator:

cmake --install build --config Release

Build system targets that are only useful for developers of this project are hidden if the aq-nwb_DEVELOPER_MODE option is disabled. Enabling this option makes tests and other developer targets and options available. You can enable the option when configuring the build by adding -Daq-nwb_DEVELOPER_MODE=ON, e.g.,:

cmake -S . -B build -Daq-nwb_DEVELOPER_MODE=ON

You can configure, build and test the project respectively with the following commands from the project root on any operating system with any build system:

cmake --preset=dev
cmake --build --preset=dev
ctest --preset=dev

Additional targets can be invoked when in development mode using the commands below

cmake --build --preset=dev --target=<name of the target>

• format-check and format-fix: run the clang-format tool on the codebase to check errors and to fix them respectively.
• spell-check and spell-fix: run the codespell tool on the codebase to check errors and to fix them respectively.
• docs : builds to documentation using Doxygen. (Note: run cmake --preset=dev -DBUILD_DOCS=ON before building to add docs target)

This project and everyone participating in it is govered by our code of conduct guidelines. By participating, you are expected to uphold this code.
