Top. Illustration of a spliced alignment between a CDS sequence g[ c] and a gene sequence h, composed of 5 blocks, 3 conserved blocks (A[ 2], A[ 4] and A[ 5]) and 2 deleted blocks (A[ 1] and A[ 3]). It induces 1 putative intron between the successive conserved blocks A[ 4] and A[ 5]. The deleted blocks A[ 1]=(k₁,l₁,a₁,b₁) and A[ 3]=(k₃,l₃,a₃,b₃) are such that a₁=b₁=0 and a₃=b₃=0. Bottom. A spliced alignment composed of 3 conserved blocks that induce 2 putative introns between A[ 1] and A[ 2] and between A[ 2] and A[ 3]
