Hello everyone again,

As a workaround for everything we talked here, i just updated
AnalyzeSkeleton with an option to display all the branch information
needed to create a graph. At the same time, I removed the log window
because the information that was being displayed there is now included
in the new "Branch information" result table:

Hope it is useful!!!
