Remove segments located inside the grain

[Saoussen-ouhiba]

Hello,

I would like to remove the segments that are located inside the grain from the list of segments of the grain boundary. Below is attached an example of the segments that I want to get rid of (indicated by the red arrow).

Can someone help me to do this please?
Thank you in advance for your help,

Saoussen

To ignore all inclusion grain boundaries you can do

% all grain boundary segments
gB = grains.boundary;

gBnotIncl = gB(~any(ismember(gB.grainId,grains(grains.isInclusion).id),2)));

plot(gBnotIncl)

All the best,

Ralf.
