title: Pan-Cancer-Nuclei-Seg-DICOM: DICOM converted Dataset of Segmented Nuclei in Hematoxylin and Eosin Stained Histopathology Images

description: 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: Pan-Cancer-Nuclei-Seg-DICOM. You can use the manifests included in this Zenodo record to download the content of the collection following the Download instructions below.

Collection description




This collection contains automatic nucleus segmentation data of 5,060 whole slide tissue images of 10 cancer types earlier published in [2] (https://doi.org/10.7937/TCIA.2019.4A4DKP9U) stored in DICOM Bulk Annotation format. Nuclei annotations are stored as closed polygons along with the area of each nuclei. The annotations correspond to digital pathology images from the TCGA-BLCA,TCGA-BRCA,TCGA-CESC,TCGA-COAD,TCGA-GBM,TCGA-LUAD,TCGA-LUSC,TCGA-PAAD,TCGA-PRAD,TCGA-READ,TCGA-SKCM,TCGA-STAD,TCGA-UCEC,TCGA-UVM collections available in NCI Imaging Data Commons.

 

To learn how these files are organized and how to access the content programmatically, see this documentation page: https://highdicom.readthedocs.io/en/latest/ann.html.

 

Conversion of the nuclei segmentations from the original CSV format into DICOM ANN format was done using the code available in 10.5281/zenodo.10632181.



Files included

A manifest file's name indicates the IDC data release in which a version of collection data was first introduced. For example, pan_cancer_nuclei_seg_dicom-collection_id-idc_v19-aws.s5cmd corresponds to the annotations for th eimages in the collection_id collection introduced in IDC data release v19. If there is a subsequent version of this Zenodo page, it will indicate when a subsequent version of the corresponding collection was introduced.

For each of the collections, the following manifest files are provided:



pan_cancer_nuclei_seg_dicom-<collection_id>-idc_v19-aws.s5cmd: manifest of files available for download from public IDC Amazon Web Services buckets

pan_cancer_nuclei_seg_dicom-<collection_id>-idc_v19-gcs.s5cmd: manifest of files available for download from public IDC Google Cloud Storage buckets

pan_cancer_nuclei_seg_dicom-<collection_id>-idc_v19-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:



install idc-index package: pip install --upgrade idc-index

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.
