On October 14, 2014, Agilent Technologies, Inc., announced that it would close its NMR (Nuclear Magnetic Resonance) business.

In an Open Letter to the NMR Community from Agilent on June 5, 2015, Agilent offered to provide free licensing of VnmrJ 4.2 for all applications, including the DOSY and CRAFT options.

At the request by many members of the NMR Community, Agilent also agreed to release the source code of VnmrJ 4.2 as “open source” by transfer of the copyright to an appropriate institutional recipient. The University of Oregon agreed to assume this role. On October 5, 2015, Agilent officials signed the transfer agreement, which was fully executed by the University of Oregon on October 8, 2015.

The open source version of VnmrJ will be known as “OpenVnmrJ”, and is a derivative of VnmrJ Version 4.2. The NMR community is indebted to Agilent, and in particular to Dan Iverson, for investing considerable effort in adapting the code of VnmrJ 4.2 for open source use. OpenVnmrJ is fully functional, suitable for use with all spectrometer systems supported by VnmrJ 4.2, and as a free-standing data application. However, users of OpenVnmrJ should be aware that installing and using it may limit your support options from Agilent – it is recommended that you retain copies of the version(s) of VnmrJ you obtained from Agilent for this purpose.

While Agilent retains the rights to VnmrJ 4.2 (and previous versions of VnmrJ), title to OpenVNMRJ is now owned by the University of Oregon.

VOSSG will assist in determining the appropriate licensing terms for release of the code to the world, any additional licensing terms for contributors, and any other ground rules/expectations. Current members of VOSSG shall determine any additions or changes to VOSSG membership.

VOSSG will also take primary responsibility for maintaining the code, documentation, and for any modifications to OpenVnmrJ, via the OpenVnmrJ project on GitHub and/or any other method chosen by VOSSG.
