Scoring matrix for nucleotide sequences:
↑ Switch it to '1PAM / κ=2' when aligning closely related DNA sequences.
Gap opening penalty: (1.0 - 3.0)
Offset value: (0.0 - 1.0)

Align unrelated segments, too? in Alpha Testing (2014/Mar)
If the input data is expected to be globally conserved but locally contaminated by unrelated segments, try 'Unalignlevel>>0' and 'Leave gappy regions'.
