OSKAR

for coordinating and recording experiments with LabVIEW and HDF5

---

@author: Adam Deller

This project was forked from PositroniumSpectroscopy/oskar.

oskar is a collection of Labview vi's that help with the tasks of (i) systematically controlling hardware and (ii) organizing acquired data using HDF5.

Essentially, it is a tool for running experiments. It was designed with a focus on:

• Hardware extensibility (it should be reasonably easy to add new control/ data-aquisition hardware).
• Structuring data for analysis.
• Recording relevant metadata (e.g., oscilloscope settings).

Installation

oskar requires LabVIEW 2015 Full Development Edition. The DAQ example `fake_camera.vi' requires the NI Vision Development Module.

• Install OpenG Toolkit, JKI JSON, and LIVE HDF5 using JKI VI package manager.
• Download and unzip oskar. Open oskar.lvproj.

Recommended:

• HDFView (for opening and exploring HDF5 files).

There are many freely available libraries for importing hdf5 data for analysis, e.g., h5py for python.

e11_analysis is a python library for processing oskar data files.

Documentation

A guide to oskar is available on the Wiki.

Example videos can be found in the media directory.

Changelog

(since forked from PositroniumSpectroscopy/oskar)

• Written in LabVIEW 2015.
• HDF5 support is achieved using LIVE HDF5.
• Simplified project structure.
• Data file has been renamed from [RID]_raw.h5 to [RID]_data.h5.
• Sequence files are saved as json instead of XML.
• The sequence-file extension has been changed from .osq to .jsq.
