Downloading data

If you have questions or feedback about the download tools provided by IDC, please reach out via our forum - we are very interested in hearing your feedback and suggestions!

IDC supports a variety of interfaces for fetching individual images, cohorts (groups of images), or portions of images, using desktop application, command-line interface, or programmatic API. These interfaces are covered in the subsequent pages. You should select the specific approach to accessing IDC data depending on your requirements.

• Download directly from IDC Portal: no prerequisites other than a Chrome web browser!

• idc-index interface: command-line and Python API interface to download images corresponding to the specific patient/study/series, or a cohort defined by a manifest

• 3D Slicer interface: desktop application to download images corresponding to the specific patient/study/series, or a cohort defined by a manifest

• s5cmd: command-line interface to download images for a cohort defined by a manifest (unlike idc-index, does not organize downloaded images into folders corresponding to IDC data model hierarchy)

• DICOMweb interface: REST API interface to access both metadata and pixel data at the granularity of image frames/tiles

• Directly loading DICOM objects from Google Cloud or AWS in Python: Python API interface to access both metadata and pixel data at the granularity of image frames/tiles
