Hi, authors, thanks for your impressive work on 3D SAM for medical image analysis.

I am downloading the LiT17 dataset from the original link provided in this repo, however the competition seems over and not allow for further downloading. Also I checked the processed data from your link. The processed data looks fine on /train folder, every volume has a seg file. But in /folder, there is only one file for each volume, from your dataset code, it seems the segment mask is combined with the raw volume,

I am not sure I understand correct, because the data format seems quite different with the original LiT17. Because I find the LiT17 format in this https://github.com/RL4M/PCRLv2/tree/finetune , and it shows every volume should pair with one seg file in train/test folder.

Looking forward to your reply!

Hi,

The LiTS 2017 released 131 volumes with labels for training and validation. For the test set, only the raw image is released. As a result, we did not use the test data in our paper. We split the original training data into our training/validation/test.

Actually, you can still download the data from the official website https://competitions.codalab.org/competitions/17094#participate-get-data, which only requires registration.

Best
