2.4 K-mer analyses of clean Illumina reads
The remaining clean Illumina reads can be used to estimate the genomic
characteristics ofC.
japonica before its genome was assembled. In the present study,
K-mer-based analysis was used to estimate the size, heterozygosity rate,
and repeat sequence of the C.
japonica genome (Liu et al., 2013). The 17-mer was selected for K-mer
analysis to ensure that enough K-mers (417) were
produced to cover the entire C. japonica genome.
