Problem with Training Data

Dear Organizers, We have downloaded the training data published in https://registry.opendata.aws/tiger/. In the guidance website, we are informed that, all of these WSIROIS data are converted to 0.5 um/px magnification, including TCGA, RUMC, JB sources. Is that right that all of them have been converted to 0.5um/px? Since we found some of them look like been scanned at 0.25 um/px.

Thanks a lot. Look forward to your reply. Best wishes, GDPH_MIA

Hi,

all slides have been converted from the original fromat based on the spacing saved in the original format. 1 slide from tcga OL had no spacing so I estimated it visually, but otherwise I trusted the original spacing. Could you please list the affected slides?
