5′ ends of flanking repeats start at position 1. Regions 5′ adjacent to the flanking repeats are indicated by negative numbers (column 1). Columns 2–13 show the most abundant bases (P), frequencies of T, C, A, G, and the total numbers of bases at the corresponding positions in Alu and ID flanking repeats. Base compositions (Comp.) of flanking repeats (bot.) and of the 5′ adjacent regions (top) are listed in the middle of the table.
