Hello, Toumi Toumi
I don't know how to use HighScore to calculate crystallinity, but actually you don't need to do it in HighScore. You can use some methods like Segal's method, or the integration method.

To calculate the degree of crystallinity using X'Pert HighScore, you generally follow these steps:
1. **Collect XRD Data:**
- Perform X-ray diffraction on your sample using an X-ray diffractometer.
- Record the diffraction pattern, which is a plot of intensity versus diffraction angle (2θ).
2. **Import Data into X'Pert HighScore:**
- Open the X'Pert HighScore software.
- Import the XRD data into the software.
3. **Baseline Correction:**
- Correct for any background or baseline signals in your XRD pattern.
4. **Peak Fitting:**
- Identify and fit the peaks in the XRD pattern.
- Peaks correspond to specific crystallographic planes in the material.
5. **Quantitative Analysis:**
- Once peaks are identified and fitted, you can perform quantitative analysis to determine the relative amounts of crystalline and amorphous phases.
6. **Calculate Crystallinity:**
- The degree of crystallinity is often calculated as the ratio of the area under the crystalline peaks to the total area under all peaks (crystalline and amorphous). This can be expressed as a percentage.
Crystallinity % =( Area under crystalline peaks/Total area under all peaks)×100
- X'Pert HighScore may have specific tools or options for calculating crystallinity. Consult the software manual or help documentation for guidance.
7. **Verify and Interpret Results:**
- Review the results and verify that the fitting of peaks and the calculation of crystallinity make sense in the context of your material.
