JCAMP-DX for Circular Dichroism Spectra and Metadata (IUPAC Recommendations 2012)

Benjamin Woollett, et al.
Pure and Applied Chemistry, 2012
Vol. 84, No. 10, pp. 2171–2182

Circular dichroism (CD) spectroscopy is a widely used technique for the characterization of proteins. A number of CD instruments are currently on the market, and there are more than a dozen synchrotron radiation circular dichroism (SRCD) beamlines in operation worldwide. All produce different output formats and contents. In order for users of CD and SRCD data to compare and contrast data and the associated recorded or unrecorded metadata, it is essential to have a common data format. For this reason, the JCAMP-DX-CD format for CD spectroscopy has been developed, based on extensive consultations with users and senior representatives of all the instrument manufacturers and beamlines, and, under the auspices of IUPAC, based on the Joint Committee on Atomic and Physical Data Exchange protocols. The availability of a common format is also important for deposition to, and access from, the Protein Circular Dichroism Data Bank, the public repository for CD and SRCD data and metadata. The JCAMP-DX-CD format can be read by standard JCAMP programs such as JSpecView. The project team also created a series of parsers, which will enable the conversion between instrument and beamline formats and the JCAMP-DX-CD format.
