Feature response curve performance on mock Even and mock Staggered communities. The y-axis shows the cumulative contig length (sorted in decreasing order) and the x-axis shows the corresponding number of misassembled contigs. The thick lines (assemblies ending in _MA) represent the results obtained by running MetAMOS using the corresponding assembler (dashed lines) for the Assembly module. (a) HMP mock Even, all errors reported (b) HMP mock Even, heavy mis-assemblies only. (c) HMP mock Staggered, all errors reported. (d) HMP mock Staggered, heavy mis-assemblies only. For all but Velvet and MetaVelvet the dashed lines are hidden behind the solid lines because the original assemblies are mostly unchanged.
