From: Aligning coding sequences with frameshift extension penalties

An alignment \((A',B')\) of length 48 between two CDS, A (13 codons) and B (14 codons). The number arrays indicate the positions of the consecutive alignment columns. Codons of A and B are colored according to the set to which they belong: IM codons in blue color, FSext codons in red color, InDel codons in green color and FSinit codons in black color. MFS nucleotides contained in FSinit codons are underlined
