Overview

Open VnmrJ (OVJ)

Open VnmrJ (OVJ) is an open-source software package designed for the acquisition, analysis, and processing of nuclear magnetic resonance (NMR) spectral data. It is an extension of the popular VnmrJ software, which was originally developed by Varian (later Agilent) for NMR data processing and acquisition. OVJ provides a flexible and customizable platform for researchers to acquire, perform advanced data analysis, and visualize NMR experiments.

OVJ offers a wide range of features and tools to facilitate NMR data processing. It includes functionalities for Fourier transformation, baseline correction, peak picking, spectral fitting, and data manipulation. OVJ supports various 1D or multi-dimensional NMR experiment types, for solution- and solid-state NMR spectroscopy.

OVJ is entirely open source. The software’s source code is freely available and can be modified and customized by the user community. This allows researchers to adapt the software to their specific needs, add new functionalities, or contribute to the development and improvement of the software itself.

The software provides a user-friendly interface, making it easily accessible to both novice and experienced users. It offers a range of visualization tools, such as 1D and 2D spectral displays, contour plots, and integration windows, to aid in data interpretation. Additionally, the software supports automation and scripting capabilities, enabling users to streamline their workflows and automate repetitive tasks.

Bridge12 Version of Open VnmrJ

Bridge12 uses a customized version of OVJ to control:

• The Bridge12 Single Channel NMR (SCN) spectrometer
• The Bridge12 Shim Power Supply (Bridge12 SPS)
• The Bridge12 Microwave Power Source (MPS) for Overhauser-DNP spectroscopy.

All functionality of OVJ is available in the Bridge12 version of OVJ, but new functionality is added to communicate with the Bridge12 instruments.
