TITLE		Mark long branches

OCCURRENCE	ARB_NT

DESCRIPTION	Badly aligned sequences often result in long branches in the
		tree. Being able to identify those branches quickly helps to
		find those sequences.

		The programs allows to mark all species having an extra
		long branch compared with it's neighbour branch.

                Enter two values separated by comma into the input field:
                   * first the minimum relative difference between two neighbour
                     branches you want to have marked.

                     Examples:

                        100 = mark branches that have more than the double length
                              compared with their neighbour branch
                        10  = mark branches that are more than 10% longer 
                        0   = mark branches that are longer than their neighbour branch

                   * second the minimun absolute difference between two neighbour
                     branches. The unit is the same as used in branchlength.

NOTES		If a branch was marked - it's parent branches will not be marked,
                i.e. the function does not mark ALL extra long branches, only those
                nearest to the tips of the trees will get marked - otherwise the
                output won't be useful.

                Intended workflow is:
                         * Search long branches
                         * Check alignment and data and maybe fix it
                         * Recalculate tree parts (see LINK{pa_add.hlp})
                         * Search again. Now you most likely will find other branches.
