[ssml] 4 different results from BLAST using blosum62 & 50.

[Kevin Karplus]

The matrix is not the whole set of parameterization for BLAST.
There are also the gap costs and the lambda and K values used for
computing E-values.

Changing the matrix without correcting the other parameters leads to
uninterpretable results.
