Normalized found intervals (percentage, categories all / any-best ) for different programs on reads from fly. The gold standard was generated with an error rate of 8% and edit distance. The programs were run with default parameters, the x axis shows the variation of error rate in the evaluation. Read set properties are as follows. [EMBL: SRR034673]: 454 reads, average length 273 bp; [EMBL: SRR026674]: Illumina reads, 36 bp; [EMBL: SRR049254]: Illumina reads, 100 bp. The key is the same for all plots. Note the different axis scalings.
