FTIR Lab v3.1

FTIR Lab is a free, beginner-friendly desktop application for processing, analyzing, annotating, and exporting publication-ready FTIR spectra.

What's New

• Cross-platform packaging — Improved build support for Windows, macOS, and Linux through GitHub Actions.
• Automatic live preview — Plot updates are now reflected automatically when plot settings change.
• Automatic typography scaling — Font sizes and typography are automatically adjusted based on figure dimensions and spectral density.
• Chemical subscripts — Chemical formulas such as CaCl₂, SiO₂, and B₂O₃ are formatted automatically without requiring special syntax.
• Individual peak-label editing — Edit peak labels independently for greater control over annotations.
• Custom plot annotations — Add and edit custom annotations directly on spectra.
• Analysis summary — Exported analysis summaries now include processing parameters and provenance information.
• Improved functional-group assignments — Refined terminology and added scientific safeguards to prevent overinterpretation.
• Official FTIR Lab logo — Added the new FTIR Lab branding.
• Offline Quran library — Includes the complete 6,236-verse offline Quran library.
• Automated scientific tests — Added permanent regression tests covering baseline correction, smoothing, peak detection, data import, chemical formatting, and Quran sequencing.
• Improved packaging workflow — Enhanced cross-platform packaging through GitHub Actions.

Scientific Note

Functional-group assignments are literature-guided suggestions, not definitive compound identification. Researchers should verify every assignment using sample chemistry, the complete spectrum, appropriate controls, and cited literature.

Windows Installation

1. Download the Windows ZIP attached to this release.
2. Extract the ZIP completely.
3. Open the extracted folder.
4. Double-click FTIR Lab v3.1.exe.

No Python installation is required.

The Windows executable has been tested before release.

macOS and Linux

Download the package corresponding to your operating system and extract it before running.

Your operating system may display a security warning because the application is not yet digitally signed.

Verification

FTIR Lab v3.1 passes eight automated scientific and data-integrity regression tests, covering core processing, analysis, data handling, formatting, and Quran sequencing functionality.

Scientific Disclaimer

FTIR Lab is designed to assist with spectral processing and analysis. Automated peak assignments and functional-group suggestions should not be treated as definitive chemical identification.

Researchers are responsible for validating interpretations using appropriate sample chemistry, controls, complete spectral information, and relevant scientific literature.

Acknowledgement

FTIR Lab is developed as an open and accessible scientific plotting and analysis tool for students and researchers.

Contributions, scientific corrections, reproducible bug reports, and improvements are welcome.
