Thanks for the report! The study you are trying to open is a slide microscopy study, which is supposed to be viewed using Slim viewer: https://viewer.imaging.datacommons.cancer.gov/slim/studies/2.25.121730171671008769235343618222969397879
How did you come up with the link that you shared?
If I open this study from IDC Portal, it correctly links to the Slim viewer.
You can use IDC skill GitHub - ImagingDataCommons/idc-claude-skill: Natural language interface to NCI Imaging Data Commons · GitHub to generate URLs, and it does point to Slim:
If you use idc-index GitHub - ImagingDataCommons/idc-index: Python package to simplify access to the data available in NCI Imaging Data Commons · GitHub you can do it this way:
from idc_index import IDCClient
client = IDCClient()
url = client.get_viewer_URL(studyInstanceUID="2.25.121730171671008769235343618222969397879")
print(url)
Hello Andrey,
Thank you for the swift response.
This link is provided by cBioPortal as the link to imaging data of the patients. You can see the example here https://www.cbioportal.org/patient/filesAndLinks?studyId=prad_tcga_pan_can_atlas_2018&caseId=TCGA-HC-A8CY

Aha! This is super-helpful!
IDC team has no control over cBioPortal, but I am adding Ino who should be able to help fix this!
@Andrei_Kiselev: I am making this post public in IDC forum https://discourse.canceridc.dev/ - you reported this issue via email, which automatically makes it private, but keeping it private makes it difficult to work on it and share with relevant collaborators. Since it does not contain any sensitive information, I decided to go ahead instead of asking for your permission - hope it is ok!
Hello.
Sure, please make it public

Andrei, sorry for the long wait, but we did meet with Ino de Briuijn @inodb and the cBioPortal team to discuss this, and we have a plan on how to move forward. We will keep you updated on this thread when there is something for you to test!
