GLUTRAN: a Matlab toolbox for glucose tracer analysis

GLUTRAN (glucose tracer analysis) is a collection of Matlab functions for the calculation of glucose fluxes in non-steady state from tracer data. GLUTRAN is based on the circulatory model for glucose kinetics described by Mari et al. (1; 2). Each function of the toolbox performs a specific task in the analysis of the tracer data; the collection of these functions allows the user to solve a variety of tracer problems. Matlab is required to perform the calculations (details on Matlab requirements and GLUTRAN installation are given in Appendix 1). The Matlab interface is a command window; the functions are thus executed as commands and not using a graphical interface (see Appendix 2 for a quick outline of the Matlab command interface). The functions used to solve a specific problem (e.g. calculation of glucose absorption and production during an oral glucose load) are typically grouped in a Matlab script and executed in sequence.
