Sending detections as nested shapes in OMERO ROIs

We have tried to upload, on OMERO, QuPath detections as nested shapes inside ROIs in two different ways

1. all detections are nested into one single ROI
2. a maximum of 5'000 nested shapes per ROIs is set and multiple ROIs are sent to OMERO.

Here is a report of those tests : QuPath-OMERO_Nested_Shapes_Tests.pdf.

Judging from low performances of the OMERO server to deal with a large number of ROIs/shapes, we decided to not send detections to OMERO. There will be no command in the extension that send detections to OMERO. However, there is still the possibility to use a public method from OmeroRawScripting API in scripts to send any pathObject to OMERO. In that case, all pathObjects will be considered as one single ROI. Therefore, if the number of pathObjects is large, OMERO limits the display to 500 ROIs per page but server performances are not guaranted in such cases.
