Peak Pairs Analysis (PPA) is a DigitalMicrograph plug-in based on the procedure developed by Pedro L. Galindo of University of Cadiz. PPA offers peak intensity analysis and local strain map calculation from standard HREM images. PPA is a complementary plug-in to GPA (Geometrical Phase Analysis) for another strain measurement plug-in.
Since the PPA handles the peak positions directly (in contrast to the GPA), we can analyze the relation between peaks, say the distances and angles (see Distortion Analysis).
