v1.0.3-beta1

QualX3 v1.0.3-beta1

This is the first beta release of QualX, a Qt6/C++ and Fortran application for qualitative analysis of powder diffraction data.

⚠️ Important: Install a reference database before using QualX

QualX requires a crystallographic reference database to perform search & match analysis. Without a database installed, the software will not be able to identify phases.

Two COD-based databases are available for download:

• one dedicated to inorganic phases
• one general-purpose database

📥 Download them here: https://www.ba.ic.cnr.it/content/old/qualx3/Databases/

For step-by-step installation instructions, please follow the procedure described on pages 7–8 of the attached qualx_manual.pdf.

Assets

• Windows installer package
• qualx-1.0.3-arm64.dmg — macOS (Apple Silicon) package
• qualx-1.0.3-x86_64.AppImage — Linux (x86_64) portable package
• qualx_manual.pdf — full user manual (includes database installation instructions on pages 7–8)

What's changed since v1.0.3-beta1

• Strongest-peaks screening in database searches now correctly uses the 2θ tolerance configured in SearchOptionsDialog (spinDelta). Previously, it used a hardcoded value converted with the wrong (inverse) formula, resulting in an excessively large tolerance that caused the screening to accept almost every card.
• Added macOS and Linux packages (.dmg for arm64, .AppImage for x86_64), alongside the existing Windows installer.

Notes

• This is a beta release: feedback and bug reports are welcome.
