RSEM-EVAL scores and BIC penalties of metatranscriptomic assemblies. The RSEM-EVAL scores computed for the assemblies generated from cRNA (diamond), ncRNA (square), and all RNA (triangle) reads by the five novo transcriptomic assemblers were indicated using the same color scheme as in Figure 1. The closer is the RSEM-EVAL score to zero, the better the assembly. The complexity of these assemblies was reflected by the Bayesian information criterion (BIC) penalty score. An assembly's complexity is assumed to be inversely proportional to its size.
