Ntdpal (NucleoTide Dynamic Programming ALignment) is a stand-alone program that provides Primer3's alignment functionality (local, a.k.a. Smith-Waterman, global, a.k.a. Needleman-Wunsch, plus "half global").
is a (positive) float (.01 precision) specifying penaltiy for creating a gap respectively (the penalties are subtracted from the output score)
is a (positive) float (.01 precision) specifying penaltiy for lengthening a gap respectively (the penalties are subtracted from the output score)
Causes the scoring matrix to be modified by dpal_set_ambiguity_codes.
Causes the end postion of the alignment in both sequences to be printed. Do not confuse with the 'e'
-f1, -f2, -f3
Force specific implementations. -f2 forces use an implementation that might provide more informative error messages, possibly at the expense of some speed.
Use a different scoring matrix: G and C matches = 3, A and T = 2, and mismatches = -0.5. (The default scoring matrix assigns 1 to a match, and -1 to a mismatch.)
Causes the alignment to be displayed on stderr.
