19 Lib ID Read length(bp) Insert Sequence Data(Mb) size(bp) depth(x) FLAjmxDEJDIAAPEI , total 16, Low quality reads were filtered, total 16.6 G data was used for further analysis, if the genome size is estimated to be 280 M in previous experiment, then the sequencing depth is expected to be 59-fold mer analysis and evaluate genome size A K-mer refers to an artificial sequence division of K nucleotides. A raw sequence read with L bp contains (L-K+1) K-mers if the length of each K-mer is K bp. The frequency of each K-mer can be calculated from the raw genome sequence reads. The K-merfrequencies along the sequence depth gradient follow a Poisson distribution in a given data set. During deduction, the genome size G=K_num/K_depth, where the K_num is the total number of K-mer, and K_depth is the frequency occurring more frequently than the others. Typically, K =

If the heterozygous rate is higher, then a small peak will be presented at 1/2 of K-mer depth. So this K-mer analysis can be used to roughly determine the heterozygous rate of a given genome. Also, this distribution can be used to determinethe repeat content of the genome, if this genome contains high proportion of repeat, then the distribution will display a fat tail which indicate more than expect proportion of the genome have a high sequencing depth which may due to sequence similarly. Conclusion: Genome size is 649Mb, and the heterozygous rate in this genome is not high so that we can do whole genome shotgun sequence and assembly. 20

Although we can t guarantee a very large length of N50, WGS is suitable to assemble this genome. 4. GC-content and Distribution analysis (Distribution of GC depth) 21

22 The x-axis presented as GC content, the y-axis represents the average depth. We used 10kb non-overlapping sliding windows and calculated the GC content and average depth among the windows. The distribution of GC content versussequencing depth will provide an eye about the sequencing bias or contamination. Usually, the genomic region with high or low GC content will possess a low sequencing depth compare to median GC content region, if the distribution of a given genome project is different from the expected pattern, it may indicate sequencing bias of contamination. If predicted to be contaminated, then we can eliminate the polluted reads by aligned the reads against bacteria, virus and fungous database. Conclusion: According to the Distribution of GC depth, we can infer that the sample has no obvious sequencing bias or contamination. 5. Conclusions and recommendations Roughly estimate the heterozygous rate of this genome: not high (<0.5%) Roughly estimate the repeat content of this genome: not high Roughly estimate the genome size of the species: about 649M Whether whole genome shotgun strategy is suitable for this genome or not: YES 22
