        {

Get image set metadata with version.

        if (AwsDoc::Medical_Imaging::getImageSetMetadata(dataStoreID, imageSetID, versionID, outputFilePath, clientConfig))

Example 1: To get image set metadata without version

The following get-image-set-metadata code example gets metadata for an image set without specifying a version.

Note: outfile is a required parameter

aws medical-imaging get-image-set-metadata \
    --datastore-id 12345678901234567890123456789012 \
    --image-set-id ea92b0d8838c72a3f25d00d13616f87e \
    studymetadata.json.gz

The returned metadata is compressed with gzip and stored in the studymetadata.json.gz file. To view the contents of the returned JSON object, you must first decompress it.

Output:

{
    "contentType": "application/json",
    "contentEncoding": "gzip"
}

Example 2: To get image set metadata with version

The following get-image-set-metadata code example gets metadata for an image set with a specified version.

Note: outfile is a required parameter

aws medical-imaging get-image-set-metadata \
    --datastore-id 12345678901234567890123456789012 \
    --image-set-id ea92b0d8838c72a3f25d00d13616f87e \
    --version-id 1 \
    studymetadata.json.gz

The returned metadata is compressed with gzip and stored in the studymetadata.json.gz file. To view the contents of the returned JSON object, you must first decompress it.

Output:

{
    "contentType": "application/json",
    "contentEncoding": "gzip"
}
