[EMBOSS] Mistake in Appdoc Edialign?

[Wolfgang Gruber]

Hello,

I studied the papers for DIALIGN and only in the newest Version
DIALIGN-TX (Subramanian u. a., 2008) I can find the information that
DIALIGN uses a guide tree. In the appdoc to edialign I read that
emboss uses DIALIGN2. In this Publikation (Morgenstern, 1999) I cannot
find an information that a guide tree is used. Also in the original
DIALIGN2 documentation I read: "This tree is constructed by applying
the UPGMA clustering method to the DIALIGN similarity scores." but
nothing that this tree is used for guiding.

So is this information in the emboss appdoc incorrect?

At all: is there a plan to update to DIALIGN-TX?

Thanks,
Wolfgang
