Dear Histai Team,

Thanks a lot for providing this large and insightful dataset.
When looking into the metadata.json for the colorectal cancer sets I stumbled upon an inconsistency in case numbers based on the metadata.json compared to the case numbers provided in your publication and huggingface repo:

Heres the code snipped I used for getting the case numbers for HISTAI-colorectal-b1 and HISTAI-colorectal-b2 form the metadata.json:

metadata = pd.DataFrame(json.load(open("path-to-json/metadata.json")))
crc_b1_df = metadata[metadata["case_mapping"].str.contains("HISTAI-colorectal-b1")]
crc_b2_df = metadata[metadata["case_mapping"].str.contains("HISTAI-colorectal-b2")]
print("HISTAI-colorectal-b1", len(crc_b1_df), "HISTAI-colorectal-b2", len(crc_b2_df))

Am I missing something? (e.g. can some cases have a different case_mapping, not including the set identifier)
Or are there cases with WSIs but no entry in the metadata.json?

Thank you already!
Best,
Lydia
