Thermo Fisher Scientific SEM to JSON

Description

The SEM to JSON component is able to intelligently extract metadata from microscopy metadata files generated through research by employing the Python Hyperspy library. For SEM data, most instruments are able to write and embed the metadata directly into the research images in TIFF format. The metadata is then extracted from these images and mapped to the existing SEM schema, resulting in a JSON metadata document adhering to the aforementioned and agreed-upon schema.

The tool has some limitations; some older SEM instruments are unable to embed the metadata in the TIFF files, and therefore an automatic extraction is not possible. This is indicated in the result file if it happens to be the case.

This component may be used to process a single research image in .tiff format, or a zipped directory containing the .tiff files may be uploaded to enable batch processing.

Input

• SEM image in .tiff format, OR;
• Compressed directory containing the SEM research images in .zip format.

Supported Vendors

Output

• Structured metadata document in .json format, OR;
• Compressed directory in .zip format containing the metadata documents for each image in the user-provided zip directory.
