handle fractional SEG objects

See original GitHub issue

Request

Related to #1345, the segmentation is encoded as fractional but we currently don’t load it.

Instead we throw this as an error:

Uncaught (in promise) Error: Fractional segmentations are not supported

What feature or change would you like to see made?

We should probably just threshold this to binary for now. Better of course would be to handle the fractional case as a kind of heatmap overlay.

Why should we prioritize this feature? It’s part of the DICOM standard and we have examples of data encoded this way.

We confirmed with @pieper that the segmentations in that kidney collections are binary, so the question is why that fractional error is coming up.

From a quick look, I am not sure how this is related to #1345 - can you clarify? Also, considering we don’t have any fractional SEGs in TCGA, and it’s not in IDC MVP, I don’t consider this to be IDC priority.

I have very limited experience with fractional SEG, I don’t think I have seen any examples other than the objects produced by BrainLab, and I don’t know of any tools that create fractional SEGs.
