Version 1.6 of Clip&Merge was tested. Version 1.7.1 of CutAdapt was evaluated together with version 1.2.11 of FLASH. We used SeqPrep version 1.1, and MergeTrimReads and LeeHom in the versions publicly available on 10 January 2015. Version 1.5.4 of AdapterRemoval was used. For the LBK1 sample, the MergeTrimReads method was not evaluated, as the run time of the method had exceeded those of all other methods when tested on smaller data sets by far. Overall, the tools Clip&Merge and MergeTrimReads performed best
