I have a DSC curve from an amorphous material. I doubt that I can accurately determine the glass transition temperature. In reviewing the literature, I see that the glass transition temperature is chosen based on visual analysis. But if there are several thermal events or the crystallization peak greatly changes the scale of the curve? Is there a computer program (open access) that can determine the glass transition temperature from the analysis of the DSC curve? Or other Jedi tricks?
Thanks in advance

How to calculate glass transition temperature from DSC curves?
How to calculate glass transition temperature from DSC curves polymer? experimental results seems different from theory.
If suitable computer software is available for automatic calculation of the glass
transition temperature
No computer software can be more useful than manual inspection. Some Jedi tricks?
1. Use little temperature ranges.
2. Repeat the experiment as many times as is necessary.
3. Keep your mind open; do not realize any result.
4. Make exhaustive research of your compound in the bibliography.
Good look
