[Seqan-dev] Blosum80 Matrix

[Hannes Hauswedell <hauswedell@mi.fu-berlin.de>]

Hey everyone,

the Blosum80 used internally in seqan is this one:
  http://www.cbcb.umd.edu/confcour/CMSC423-materials/BLOSUM80.txt
which says "Matrix made by matblas from blosum80_3.iij"

However most other references to Blosum80 on the web refer to this one:
  http://www.cs.ucf.edu/courses/cap5937/fall2004/assignment2/BLOSUM80
which says "Matrix made by matblas from blosum80.iij"

They do differ quite a bit. Does anyone know the background? Why was one 
chosen over the other?

Regards,
Hannes
