Merge grains having boundaries in common

[Saoussen-ouhiba]

Hello,

I have the following EBSD map.

I was able to determine island grains from this EBSD map as see in the following figure

I would like now to merge the island grains that have boundaries in common. Is there a function to identify these grains please?
Thank you a lot,

Saoussen

Hi,
if I understand you correctly, the following should be an example of what your try to do:

mtexdata twins;
grains = ebsd.calcGrains('angle',1*degree');
cinc = grains.isInclusion;

% that looks a bit complicated
gbm = grains(cinc).boundary(all(ismember(grains(cinc).boundary.grainId,grains(cinc).id),2))

migrains = merge(grains,gbm)

plot(grains(cinc))
hold on
plot(gbm,'linecolor','r')
hold on% merge inclusions
plot(migrains(migrains.isInclusion).boundary,'linecolor','g')
hold off

Cheers,
Rüdiger
