Hi @neheller, I recently decided to submit my work on the KiTS 21 challenge. I downloaded the dataset (300 cases) and have the following queries to start my work:
In the case folder (for ex. case_00000), there are 2 directories (raw, segmentations) and 4 other files (3 aggregate segmented results with AND, OR, and MAJ, 1 is image file). Question: which segmented result, I need to consider out of these (specific any one or all) for the experiment (training)?
Should I need to use segmented files from the segmentations folder? Why there are three annotations for each instance? Here I know, instances for two kidneys and three annotations for three different persons. But, my confusion is: How can we combine the segmented labels of different persons (different annotations)?
For the experiment, should I need to do anything with the files under the raw folder?
As per the requirements of this challenge, we need to segment kidney, tumor, and Cyst. However, in the segmentations directory information about kidney and tumor is given (like kidney_instance-1_annotation-1.nii.gz, tumor_instance-1_annotation-3.nii.gz). What about Cyst?
I am not familiar with this dataset, so my question may be basic. However, I expect a response soon. Thanks in advance.
