Quasar is an open‑source suite of spectroscopic data‑analysis tools built on the Orange machine‑learning and visualization platform. It enables users of all experience levels to create dynamic, reproducible workflows that integrate spectral processing, hyperspectral mapping, and multivariate analysis. (Orange, 2013)
If you’re new to Quasar, explore our Getting Started guide, Tutorials, Tips and tricks and example Workflows to begin working with FTIR data.
Quasar offers fast, flexible spectral‑processing tools—baseline subtraction, normalization, FFT, EMSC, peak analysis, differentiation, smoothing, and more. These features can be combined with sample metadata for multivariate methods such as regression, classification, clustering, PCA, and hierarchical analysis. Workflows can be shared to ensure consistent, reproducible analysis across projects.
Advanced users can integrate custom Python code or figures directly into workflows, leveraging the broader scientific Python ecosystem. Community contributions are welcome. Connect with beamline staff to learn more, request new features or share your data‑processing needs. We’re here to support your analysis.
