These values can range from 0 to length-1 of the sequence. A description of the error will be displayed in the DNAScriptor dialog message box and if open, the debug display window. The returned value will always range between 0 and length-1 of the longest sequence. Remarks These functions can consume very large amounts of memory and time for large sequences. This however is often not a practical limit since sequences of that size will take hours to globally align.
Practical alignments are usually a few thousand nucleotides.
Both DNA and protein global alignments require a Matrix file containing the weighting values using for matching residues. The matrix file used, is the current default DNA or protein matrix file as set by the SetDefaultMatrixFile function . Also the gap penalty and gap extension parameters need to be defined using the SetGlobalAlignParameters and SetDefaultGlobalAlignParameters functions. SetDefaultMatrixFile, GlobalAlignRegion , IsIdentical. This function allows the Global Alignment parameters for a gap and a gap penalty to be set.
