  1. The alternative measures are defined in the main text. The evaluated assemblies were produced by Trinity, Oases, SOAPdenovo-Trans and Trans-ABySS, based on the subset of reads in the real (strand non-specific) mouse data that align to genes on chromosome 1. This subset was used in the interest of computational efficiency of the alternative measures. KC score, k-mer compression score.
