WebOct 24, 2016 · An example of multiple alignment. Gaps are added to adjust sequences. In this example, there are 3 site matches before alignment. After multiple alignment, there are 14 site match. WebA guide tree is generated at the first step of multiple alignment. It can be used as a rough clustering of unaligned sequences, to divide the input sequences into several closely related groups. MAFFT outputs just the guide tree without alinging the sequences by: % mafft --retree 0 --treeout input > output

WebMAFFT is a multiple sequence alignment program for unix-like operating systems. It offers a range of multiple alignment methods, L-INS-i (accurate; recommended for <200 sequences), FFT-NS-2 (fast; recommended for >2,000 sequences), etc . Merits (Accuracy) L-INS-i is one of the most accurate multiple sequence alignment methods currently available. WebMAFFT offers various multiple alignment strategies.
