Materials Science EM Metadata Extractor

A collection of Python scripts that extract metadata from EM data for Materials Science. All metadata files are in json format.

1. hyperspy_script:

   • Uses python v3.10.12 and hyperspy v1.7.5
   • Working only for .emd files, .prz files are not recongized by this version of hyperspy
   • Output directory: 'hyperspy_script_metadata/'

2. rsciio_script:

   • Uses python v3.11.9 and the latest version of hyperspy (v2.1) which essentially leads to RosettaSciIO library (rosettasciio v0.4)
   • Working for both .emd and .prz files, with the exception of EELSDataCube Single Image, which is still unsupported
   • Output directory: 'rsciio_script_metadata/'

3. manual_script:

   • Uses python v3.11.9, numpy v1.26.4 and h5py v3.9.0
   • Working for all input files, however in some cases the metadata is lacking information
   • Output directory: 'manual_script_metadata/'

4. final_script: (WIP)

   • Uses python v3.11.9, rosettasciio v0.4 and numpy v1.26.4
   • Same as rsciio_script but for the unsupported .prz file it uses numpy as seen in manual_script
   • Output directory: 'final_script_metadata/'
