!!NA_SCORING_MATRIX_RECT 1.0 Default (from upam.gbl) scoring matrix used by FASTA for the comparison of nucleic acid sequences. FASTA uses the method of Pearson and Lipman to find sequences in a data library that are similar to a query sequence. This matrix was updated for FASTA version 2.0, and thus differs from the older versions of the matrix.
