In vivo magnetic resonance spectroscopy provides insight into metabolism in the human body. New acquisition protocols are often proposed to improve quality or efficiency of data collection. Processing pipelines must also be developed use these optimally. Current fitting software is either targeted at general fitting, for specific protocols. We therefore introduce MATLAB-based OXford Spectroscopy Analysis (OXSA) toolbox allow researchers rapidly develop their own customised processing pipelines. The aims simplify development by: being easy install and use; seamlessly importing Siemens Digital Imaging Communications Medicine (DICOM) standard data; allowing visualisation offering a robust routine; flexibly specifying prior knowledge when fitting; batch spectra. This article demonstrates how each criteria have been fulfilled, gives technical details about implementation MATLAB. code freely available download from https://github.com/oxsatoolbox/oxsa.
