الوصف: |
Reads were simulated from the four species (indicated on right) as described under the “Demonstration” heading of the Design and Implementation section of the manuscript. Above kmer size of 18 little difference is observed in the number of unique kmers extracted. Kmer sizes from 1 to 18 show a marked increase as kmer frequency as size is incremented in steps of 1. This indicates that for these small kmers, shared kmers by chance (or kmer collisions) between different gene families and gene regions are more likely. For example, for kmer sizes of 4 there are only 256 unique permutations to describe the entire read dataset. Assemblies using kmers of this size would produce spurious sets of contigs that are highly chimeric. The three assemblers used in this study were Trinity, CStone and rnaSPAdes and have default kmer sizes of 25, 40 and 55 respectively, as indicated with the dashed vertical lines. (TIF) |
