In the last month I've written an abstract for the ISMANAM'2013 conference
that will be held in June in Torino, Italy. The corresponding poster and
paper will concern methods for identification of symmetric and
quasi-symmetric boundaries. We started to look for more efficient
methods for quantification of mixed boundaries. Until now, we have
distances to the nearest tilt and twist boundaries, which are correct
and very complicated and time-consuming to calculate, and we have
Fortes decomposition which is fast, but unstable.
