Get A Listing Of All Resource Folders Stored With An Experiment

For an image session, this only URI only returns resources stored with the experiment, not any resources stored at the scan or image assessor context. See Image Session Scans API and Image Assessor Resource API for details.

CODE

GET - /data/projects/{project-id}/subjects/{subject-id | subject-label}/experiments/{experiment-id | experiment-label}/resources
GET - /data/experiments/{experiment-id}/resources

Parameters

{project-id}	Path parameter
{subject-id} or {subject-label}	Path parameter. Subject label is a project-specific field, and can only be used if a project is specified.
{experiment-id} or {experiment-label}	Path parameter. Experiment label is a project-specific field, and can only be used if a project is specified.
format	Optional querystring parameter. Specify the format of the returned response. json (default) html xml csv
sortBy	Optional querystring parameter: Sort the returned results by one or more parameters in the Result array. Multiple parameters can be provided, separated by commas.

Response

This call returns an array of resource descriptors, where the key values are "xnat_abstractresource_id" and "label", which can be used as a path parameter.

GET - /data/projects/{project-id}/subjects/{subject-id | subject-label}/experiments/{experiment-id | experiment-label}/resources/{resource-id | resource-label}/files/{filename}
GET - /data/experiments/{experiment-id}/resources/{resource-id}/files/{filename}

Parameters

{project-id}	Path parameter
{subject-id} or {subject-label}	Path parameter. Subject label is a project-specific field, and can only be used if a project is specified.
{experiment-id} or {experiment-label}	Path parameter. Experiment label is a project-specific field, and can only be used if a project is specified.
{resource-id} or {resource-label}	Path parameter.
{filename}	Path parameter.

Response

Success (200) returns the file in its native format.
