Spectral data of Bragg-edge imaging, which is one of the energy-resolved neutron imaging methods, can be analyzed by single-edge analysis and full-pattern analysis with the Bragg-edge analysis code RITS developed by Sato et al. This program has a function to generate neutron transmission data considering wavelength-dependent pulse-shape function, atomic number density, crystalline structure, etc., and to extract these parameters from the measured data by the nonlinear least-squares fitting. Last year, we worked on updating the operating environment of the platform Scientific Linux 6 and the language Python 2, which have been discontinued, to Windows 10 and Python 3, and added some functions to improve usability. GUI-RITS for the windows platform has been released to users. In this presentation, we will show concrete examples of the results of the analysis of the same data by the old and new programs, and compare the efficiency of data analysis.
