DICOM converted Slide Microscopy images for the TCGA-MESO collection

This dataset corresponds to a collection of images and/or image-derived data available from National Cancer Institute Imaging Data Commons (IDC) [1]. This dataset was converted into DICOM representation and ingested by the IDC team. You can explore and visualize the corresponding images using IDC Portal here: TCGA-MESO. You can use the manifests included in this Zenodo record to download the content of the collection following the Download instructions below.

Collection description

Mesothelioma is a rare cancer that affects the thin layer of tissue that lines the chest, abdominal cavities, and most of the organs within them. This lining is called the mesothelium. In the United States, there are roughly 3,000 new cases diagnosed each year. Exposure to asbestos is the main risk factor for developing this disease, and men tend to be more commonly affected— a fact that most likely correlates with men holding jobs where they are more likely to come in contact with it.

Please see the TCGA-MESO information page to learn more about the images and to obtain any supporting metadata for this collection.

Files included

A manifest file's name indicates the IDC data release in which a version of collection data was first introduced. For example, collection_id-idc_v8-aws.s5cmd corresponds to the contents of the collection_id collection introduced in IDC data release v8. If there is a subsequent version of this Zenodo page, it will indicate when a subsequent version of the corresponding collection was introduced.

1. tcga_meso-idc_v10-aws.s5cmd: manifest of files available for download from public IDC Amazon Web Services buckets
2. tcga_meso-idc_v10-gcs.s5cmd: manifest of files available for download from public IDC Google Cloud Storage buckets
3. tcga_meso-idc_v10-dcf.dcf: Gen3 manifest (for details see https://learn.canceridc.dev/data/organization-of-data/guids-and-uuids)

Note that manifest files that end in -aws.s5cmd reference files stored in Amazon Web Services (AWS) buckets, while -gcs.s5cmd reference files in Google Cloud Storage. The actual files are identical and are mirrored between AWS and GCP.

Download instructions

Each of the manifests include instructions in the header on how to download the included files.

To download the files using .s5cmd manifests:

1. install idc-index package: pip install --upgrade idc-index
2. download the files referenced by manifests included in this dataset by passing the .s5cmd manifest file: idc download manifest.s5cmd.

To download the files using .dcf manifest, see manifest header.
