Fast statistical alignment
FSA is a multiple sequence alignment program for aligning many proteins or RNAs or long genomic DNA sequences. Along with MUSCLE and MAFFT, FSA is one of the few sequence alignment programs which can align datasets of hundreds or thousands of sequences. FSA uses a different optimization criterion which allows it to more reliably identify non-homologous sequences than these other programs, although this increased accuracy comes at the cost of decreased speed.
