Return NUC44 scoring matrix for nucleotide sequences
ScoringMatrix = nuc44
[ScoringMatrix, MatrixInfo] = nuc44
ScoringMatrix = nuc44 returns the scoring matrix. The nuc44 scoring matrix uses ambiguous nucleotide codes and probabilities rounded to the nearest integer.
Scale = 0.277316
Expected score = -1.7495024, Entropy = 0.5164710 bits
Lowest score = -4, Highest score = 5
Order: A C G T R Y K M S W B D H V N
[ScoringMatrix, MatrixInfo] = nuc44 returns a structure with information about the matrix with fields Name and Order.
Note: The NUC44 scoring matrix is supplied by NCBI and is used by the BLAST suite of programs. For more information, see ftp://ftp.ncbi.nih.gov/blast/matrices/.
