[Insight-users] How to create a LabelMap or Label object

[Anja Ende]

Hi Xabi,

Thanks for the reply. However, is it not possible to create a label
simply based on the points. When the user delineates the object, I
usually have the connected points and it would be much more efficient
for me to use these points.

Cheers,
Anja
