Due to the recent changes in the segmentation plugin there are now two possible ways views require nodes to be selected.

Segmentation:
Choose nodes in drop down boxes

Diffusion views:
Select nodes in Datamanager (multiple with CTRL + click ) and display selected nodes in text label

Problem:
Especially the second choice is not obvious for medical users and they might try to click the labels in order to get the dropdown menu to show.

Possible Solution:
Combine the two approaches. Every view has comboboxes for the selection of data. But if you select images in the datamanager the comboboxes automatically update.

Remaining problem:
The views do not know which nodes have been selected in other views. E.g. if you are segmenting a ROI in the segmentation view and switch to the IVIM view the corresponding data nodes will not be selected.
