Jeol SEM to JSON

Description

The Jeol SEM to JSON mapper converts metadata from Jeol Scanning Electron Microscope (SEM) output into a structured JSON document that follows the defined SEM schema. During an experiment using the SEM technique with Jeol instrument, the acquisition metadata are saved in plain-text .txt files and stored along with the corresponding image. The mapper reads and parses these .txt metadata files, normalizes and validates key fields, and maps the extracted values into the agreed-upon schema using the Python Pydantic library.

This component may be used to process a single acquisition metadata file in .txt format, and with a later version, a zipped directory containing the .txt files may be uploaded to enable batch processing.

The source code is available here.

Input

• Jeol.txt file in the same directory as the image files.
