NOVENA 4D STEM ANALYSIS AND VISUALIZATION

NOVENA is a fast and easy-to-use program that enables the display and analysis of large 4D STEM datasets in the DECTRIS H5 format. It offers an intuitive interface for defining virtual detectors, and calculating and visualizing a range of image types. Conversion of non-DECTRIS data formats is possible using our format conversion tool (see section below on this page).

NOVENA is freely available via the download link below.

Key Features:

• Fast data loading and optimized memory management
• Simultaneous display of image and diffraction space
• Virtual STEM image calculation and visualization
• Center-of-mass (CoM) image calculation and visualization
• Differential Phase-Contrast (DPC) image calculation and visualization
• Vector field (E field and B field) animation
• Interactive Fourier Filtering

System Requirements: Windows 10 / 11 (x64) operating system; Intel Core i5 processor or equivalent (i7 and higher recommended); 16 GB of RAM (32 GB or more recommended); internal solid-state drive.

We provide a tool to convert other (non-DECTRIS) 4D STEM data formats, so that they can be used with NOVENA. The converter works for EMPAD data, K2/3 data (DM4 format), and raw binary data. Other formats may be added if requested.

The conversion tool is freely available via the download link below. It requires a license (freely available) to run. Just install it and run it, and follow the steps to obtain a free license.
