Hello,

Thanks for the suggestions. I am successful in segmenting the only
filament-like structures.  But I have not really understood what Dr. Volko
suggested for the selection of the structures. May I request you to tell me
the details? The image which was attached by Dr. Volko is the exact one I
intend to do.

For the convenience, I have attached my image after filtering only
tube-like structures.

Thanks
Anu
