Image Metadata

Hi, I downloaded the dataset from Stanford AIMI (https://stanfordaimi.azurewebsites.net/datasets/72dd9b3a-3a21-49ce-9583-be644d792f01 if it doesn't open in Chrome try with Safari) and realized that it's unfortunately in .npy format, without the important image metadata like spacing, thickness, orientation, etc.

I unsuccessfully tried to find the CT voxel spacing in the paper and the supplemental. This dataset would be great to use in combination with, e.g., nnUNet, but in order to convert it to nrrd/nifti, the missing metadata is crucial. Is that metadata available anywhere? If not, would you happen to know if they were all resampled to a particular voxel spacing before npy conversion?

I see that this repository mentions HDF5 that contains image metadata. Is that version of the dataset available somewhere?

Thank you!
