Access to the synapse multi-organ dataset:
1. Sign up in the [official Synapse website](https://www.synapse.org/#!Synapse:syn3193805/wiki/) and download the dataset. Convert them to numpy format, clip the images within [-125, 275], normalize each 3D image to [0, 1], and extract 2D slices from 3D volume for training cases while keeping the 3D volume in h5 format for testing cases.
