Errors and Ns corrected by the merging programs. a Error rates in the paired reads’ overlap regions, before and after the application of the merging programs. Note that the “Before” error rates vary because different merging programs analyze slightly different sets of reads (see Additional file 2: Table S1). b Total number of Ns corrected by each of the merging programs
