a.s.ist Inc. (hereinafter 'a.s.ist') is promoting the digital transformation (DX) of the manufacturing industry using white-box AI, based on research knowledge cultivated at the University of Tokyo.
We are pleased to announce the start of a 7-day free trial for 'AutoStatSpectra,' a spectral analysis software based on Bayesian statistics. During the trial period, all features can be used without restrictions.
*The term 'World's First' in the title is based on our company's research as of April 2026.
7-Day Free Trial Started for 'AutoStatSpectra', Automating Spectral Analysis with Bayesian Statistics
■ Background of Development
In spectral analyses such as XPS (X-ray Photoelectron Spectroscopy), FT-IR (Fourier Transform Infrared Spectroscopy), and NMR (Nuclear Magnetic Resonance), how overlapping peaks are separated, and how the number of peaks, parameters for each peak, and peak function shapes are set greatly affect the analysis results.
However, conventional curve-fitting software often relies on the analyst's experience and trial-and-error for these settings, leading to issues with the objectivity and reproducibility of the results.
AutoStatSpectra realizes the automatic estimation of the number of peaks, peak parameters, and peak function shapes, as well as the quantification of the uncertainty of estimated values through Bayesian inference. It provides statistically backed spectral analysis that does not depend on the subjective view of the analyst.
■ Main Features of AutoStatSpectra
AutoStatSpectra Analysis Flow
Automatic Estimation of Peak Numbers, Parameters, and Function Shapes
It compares models within a specified range and automatically selects the optimal number of peaks based on posterior probabilities. Furthermore, in addition to parameters such as the height, center position, and half-width of each peak, it automatically estimates suitable candidates for peak function shapes like Gaussian, Lorentzian, and Pseudo-Voigt functions tailored to the data. Since the uncertainty of each estimated value can also be evaluated quantitatively, it achieves highly reproducible peak fitting that is less dependent on the analyst's experience or trial-and-error.
Versatile Background Correction
In addition to constant and linear backgrounds, it supports multiple background corrections including the Shirley method for XPS. Preprocessing tailored to various measurement methods can be flexibly selected.
Batch Analysis of Multiple Files (Multi-file Workspace)
Multiple spectral data can be combined into a single workspace for batch processing under common analysis conditions. This supports efficient analysis of large amounts of data, such as condition studies and comparisons of changes over time.
Automatic Generation of Analysis Reports
It automatically outputs analysis results as a PDF/Word report. Comprehensive reports including fitting plots, model comparison tables, parameter lists, and posterior distribution charts significantly shorten the workflow from analysis to reporting. It also supports data export to CSV and Excel.
Support for Diverse Data Formats
It widely supports various data formats such as CSV, Excel, VAMAS, and SOF-H.
