a–j Distribution of predicted change in repeat copy number, for nanopore reads from each of ten plasmids. Red arrows: expected copy number change. Forward (red) and reverse strand reads (blue) are shown separately. y-axis: read count, x-axis: change in copy number relative to the reference plasmid. Reference copy numbers in each plasmid are in Additional file 1: Table S7. Black arrows: reads in these peaks may actually have shortened repeats
