# GatanReader

This page lists supported metadata fields for the Bio-Formats Gatan Digital Micrograph format reader.

These fields are from the OME data model. Bio-Formats standardizes each format’s original metadata to and from the OME data model so that you can work with a particular piece of metadata (e.g. physical width of the image in microns) in a format-independent way.

Of the 476 fields documented in the metadata summary table:

  - The file format itself supports 69 of them (14%).

  - Of those, Bio-Formats fully or partially converts 69 (100%).
