Reads quantities and subsequent spacer number as convergent proofs of duplications, the case of ERR718201. Reads quantity are shown in blue. The number of the following spacer is shown in red crosses. *: spacers showing twice more reads than the average. Note that spacers 14,15,17,18,19,20,21 show twice more reads. Conversely spacer 21 is followed sometimes by spacer 22, sometimes by spacer 14. This is compatible with a duplication of the region spacer14-spacer21, with one repetition lacking spacer 16. Also note that the deletions are documented both by the absence of reads for the concerned spacers, and by a subsequent spacer (for instance spacer 9 deletion confirmed by the fact that spacer 8 is followed by spacer 10)
