fftnsi description

FFT-NS-i is a subtype of the MAFFT alignment which uses iterative refinement method with two cycles only. It is a fast alignment method oriented on speed alignment

Parent program: mafft

MAFFT is a multiple sequence alignment program for amino acid or nucleotide sequences that uses fast Fourier transform and simplified scoring system to rapidly identify homologous regions between sequences. MAFFT performs well in reducing CPU time required for multiple sequence alignment and allows an increased the accuracy of alignments even for sequences with large insertions or extensions as well as distantly related sequences of similar length. It offers a range of multiple alignment methods, L-INS-i (accurate; for alignment of < 200 sequences), FFT-NS-2 (fast; for alignment of < 30,000 sequences), etc. The type of input sequences (amino acid or nucleotide) is automatically recognized.
