This is the code accompanying the paper "Real-time interactive 4D-STEM phase-contrast imaging from electron event representation data" to come out in IEEE Signal processing. The functionality can be seen in the two example notebooks in the 'examples' folder.

Please download the necessary data from here and here and put them in the example directory

You can then set up a conda environment with all dependencies like so:

conda env create -f environment.yml
conda activate cu11

Colin Ophus (NCEM/LBL)

Peter Ercius (NCEM/LBL)

Mary Scott (NCEM/UCB)

Ian Johnson (former LBL)

Before committing, run

nbdev_build_lib && nbdev_clean_nbs && nbdev_build_docs

to compile the notebook into script files, clean the notebooks, and build the documentation.

Do not edit this README directly, rather edit index.ipynb and regenerate the README.
