I want to apply geometric phase analysis (GPA) using GPA phase plug-in in digital micrograph software (both in 2.3.2 and 3.4 version) and it shows a "dll initialization is failed" during the start-up and shows error during power spectrum generation. How to fix it? I have uploaded the plug-ins by copy and pasting the "dll" files and "help" files in the corresponding folder. You can suggest any effective alternative method also. It will be very much helpful.
