Launching an external application and regularly checking if it is still running
DigitalMicrograph - Gatan
Example script showing how the external application Notepad.exe can be launched. The script regularly polls whether or not Notepad.exe is still open so that actions can be performed once the external application is closed.
Live difference
Python - Gatan
Code to process the live-view image in DigitalMicrograph, producing a difference image. Two exponentially weighted moving averages are computed, and the absolute value of the difference between them is returned.
Live FFT color map
Python - Gatan
Code to process the live-view image in DigitalMicrograph, producing a series of maps of crystalline regions in real-time. It computes a grid of small FFTs from each image. It then treats this grid similar to a 4D STEM data cube, where it finds the brightest spot in each FFT and displays its orientation and intensity as an updating color map.
Live max FFT
Python - Gatan
Code to process the live-view image in DigitalMicrograph, producing an FFT-like display. A grid of small FFTs is computed from the image, and then rather than averaging the FFTs together, the maximum across all FFTs is taken pixel-by-pixel.
Live noise reduction
Python - Gatan
Code to process the live-view image in DigitalMicrograph, producing a new filtered display. A median and/or Gaussian blur can be applied.
Live radial profile
Python - Gatan
Code to compute radial-max profiles of the FFT of a live-view image in DigitalMicrograph, producing a 2D display of these profiles over time.
Live simple copy
Python - Gatan
Code to process the live-view image in DigitalMicrograph, producing a copy. This script provides a minimal template for processing data in the live view.
Live thresholding with plots
Python - Gatan
Code to process the live-view image in DigitalMicrograph, producing a binary display. The live image is thresholded, and several morphological operations are applied to create a binary display. Then the largest contiguous bright region is found and circled. A plot of the position of the center of mass of that bright region is also updated live.
LiveView linear profile
Python - Gatan
Compute ROI-based profiles over time from the LiveView image in Gatan Microscopy Suite.
