# Introduction

QualX is designed around a simple workflow:

    Import pattern → Data Reduction → Search & Match → Accept phases

## Main Window

The main window is divided into several panels:

- Graphic area (centre): displays the diffraction pattern, background, peaks and accepted phase reflections
- Results List (bottom/right dock): ranked list of candidate phases
- Peaks (dock): list of experimental peaks
- Peak Compare (dock): overlay of selected card reflections vs. experimental peaks
- Quantitative (dock): accepted phases with RIR percentages. The RIR value is actively used to perform a semi-quantitative analysis, shown as a pie chart
- Report (dock): summary report of the analysis

## Workflow Overview

1. Import a diffraction pattern (File → Import Diffraction Pattern)
2. Background: estimate and optionally subtract the background
3. Peak Search: detect peak positions and intensities
4. Search/Match: query the database and rank candidate phases by FOM
5. Accept: move identified phases to the Quantitative panel
6. Save the project (.qxp) to resume later
