Low coverage z-score ranking based on 36 evaluation statistics for de novo and reference-guided de novo assembly approaches with and without step 5. The cumulative z-score ranking (a) based on 36 evaluation statistics between the different low coverage assembly approaches. Error bars correspond to the best and worst summed z-score that could be reached by omitting one evaluation statistic from the analysis. De novo assembly programs are shown in orange and reference-guided de novo assembly approaches with step 5 (refG) in red and without step 5 (oRefG) in light red. The violin plots of z-scores from the low coverage data set are shown in (b) in which the white points correspond to medians, black boxes to interquartile ranges and the orange/red areas to the kernel density estimations of the z-scores. The lines and stars indicate significant higher z-scores (*: p-value <0.05, **: p-value <0.01)
