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).

Distortion Analysis from v4.0
Distortion Analysis allows you to analyze inter-peak distances and angles from peak-pair information and peak positions of complex structures.Read More

Non-Local Average module (the NLA module license is requires)
The Non-Local Average (NLA) module gives an averaged image over a time-series images (a sequence of images obtained by repeating the measurements on the same object). Even without the NLA license, using the Script version you can evaluate the functionality of the NLA module. Read More
