Regarding Partial Annotation Storage and Retrieval in MONAI Label and 3D Slicer

[Suchi97]

Hi Team,

We are in the process of annotating over 70 labels using both 3D Slicer and MONAI Label. FYI, our 3D Slicer is locally installed on our computer, while the MONAI Label Server is running on our DGX Server.

Our objective is to preserve partial annotations and import the same file to seamlessly continue the annotation process.
We have discovered a method to save annotations locally, and the steps to achieve this are outlined below:

1. Utilize the save button in 3D Slicer to store the partial annotation. This action generates a file in the .nrrd format, saved within the local directory.
2. To reload the partial annotation, used the add button in 3D Slicer and navigate to the saved directory.

Our inquiry pertains to whether there is similar functionality in the MONAI Label Server that allows for the preservation of partially annotated labels and subsequent reloading to facilitate a smoother annotation process.

Any help is appreciated.
Thanks in advance

I don't think MONAI Label server supports that, but maybe others here can comment.

I've always followed the same path you describe, where we use Slicer's native tools to perform annotations, saving and restoring work as we go, and then use a script to assemble them for training using MONAI Label. This seems to work well for the clinical annotators.
