Effect of cluster density on paired-end PBAT-seq (IMR-90). a Quality scores assigned to the four bases in R2 generated using HCS v2.2.38 at different cluster densities. The quality scores in R2 of PhiX control on the same flow cell are also shown. b Quality scores assigned to Cs in R2 generated using different HCS versions at different cluster densities. c Quality scores assigned to the four bases in R1 and R2 generated using the latest HCS v2.2.58 at a modest cluster density (483Â K per mm2). The quality scores in R2 of PhiX control on the same flow cell are also shown
