How to do the preprocessing step?

[Myrrolinz]

I want to use verse'19 dataset, but I haven't figure out what I need to do first. Thank you for your kindly help!

我看见您写道：We follow the z-score normalization strategy in nnUNet to preprocess clean and fused lobe datasets, VerSe'19 and LA/LAA dataset.
具体应该如何实施？

That is a common normalization strategy by introducing mean values and variations. Please refer to nnUNet for more details.

I want to know whether dataloader should be preprocessed before using the normalization strategy, and whether rawdata should be directly converted into img sequence in nnUNet for normalization when using the normalization strategy. What do z-score normalization img and seg input when normalizing derivatives.
