Question about MAISI data preprocessing

Hi,

I'm preparing the data for finetuning MAISI's ControlNet. I have some questions about the 3D VISTA segmentation.

1. How does a VISTA output pseudo label merge with the original label? Are the existing classes in the original label used directly? If it overlaps with other classes, do the existing classes apply?
2. Should I simply remove the prediction mask of dummy classes in label_dict? For example, the kidney is set to dummy1.

Thank you in advance for your help. It would be great if you could provide the official implementation of the merging original and pseudo labels.

Best,
Yu-Cheng
