4D-Explorer

4D-Explorer is a software to analyze four-dimensional scanning transmission electron microscopy (4D-STEM) data. It can import and save 4D-STEM datasets and their metadata, calibrate them and reconstruct images in real space. See Colin Ohpus, 2019 for more information.

Installation FourDExplorer from Executable

From releases page of GitHub, we download packages according to the operating system. Currently, Windows 10, Windows 11 and MacOS are supported. For Linux, see Installation FourDExplorer from Source instead.

Next, unzip the downloaded packages, and execute 4D-Explorer.exe to open the software.

Installation FourDExplorer from PyPI

It is recommended to use Anaconda to set up the programming environment:

conda update conda
conda create -n FourDExplorer python==3.10
conda activate FourDExplorer
pip install --upgrade FourDExplorer

Then, run python

python

Now, we import the FourDExplorer module and run the GUI:

>>> from FourDExplorer import FourDExplorer
>>> FourDExplorer.run()

Test Data

We provide three sets of test data, namely gold_nanoparticle_06, gold_nanoparticle_07, and MoS2_14. The download links for these datasets are as follows:

• Google Drive: 4D-Explorer Test Dataset
• Baidu Netdisk: 4D-Explorer Test Dataset, Extraction Code: 64s2

The parameters of the test data can be found in the 4D-Explorer Docs: Test Data

Documentation and Tutorials

See 4D-Explorer Docs for detailed documentation and tutorials.

Performance

4D-Explorer never read the whole dataset into memory at once. It usually does not require large memory for computing.
