Dear Sermin,
You should not get holes in structures.
You should also not use FIRST with children younger than 4 years
old, as that is the limit of the age range for the training data used.
If it helps you can upload an example segmentation (and original
image) to:
http://www.fmrib.ox.ac.uk/cgi-bin/upload.cgi
and send us the reference number so that we can see the problem.
All the best,
Mark

Why does this happen? and how can this be avoided? Our study goes on children and the brain-maturation. Does the program have any problems dealing with a child's brain? I've tried to read the Technical report/thesis by Brian Patenuade but without success.
