nexusLIMS.extractors.plugins.profiles.fei_titan_tem_642.parse_tecnai_metadata(metadata: dict[str, Any], context: ExtractionContext) → dict[str, Any][source]#

Parse Tecnai-specific metadata from ImageTags.Tecnai.Microscope_Info.

The 642 Titan TEM stores extensive microscope parameters in a delimited string format that needs special parsing.

Parameters:

  • metadata – Metadata dictionary with ‘nx_meta’ key

  • context – Extraction context (unused but required by profile signature)

Returns:

Modified metadata dictionary with parsed Tecnai metadata

Return type:

dict

The 642 TEM indicates diffraction via specific Mode strings.

Parameters:

  • metadata – Metadata dictionary with ‘nx_meta’ key

  • context – Extraction context (unused but required by profile signature)

Returns:

Modified metadata dictionary with updated dataset type if applicable

Return type:

dict
