Jellyfish genome size
WebAlso, it makes more sense to plot these things as log-log rather than linear-linear; And the y-axis should are count, not frequency, which are useless for the purpose of genome-size estimation.

WebThe genome size estimated by flow cytometry for the Leucocoprinus sp. from C. costatus is smaller than that estimated by most of the assemblies we obtained for this sample (table 1). In general, most assemblers using short-read sequence data have problems in compiling and assembling reads from long tandem repeat regions of the genome. WebThe current version does not have any limitation on the size of k-mers, unlike version 1.1 which was limited to k = 31. The support for Quake has been dropped in the new version, use version 1.1 with Quake. The User guide gives some information on how to use Jellyfish and the differences between the new and old versions. Contact
WebGenome size can be calculated by counting k-mer frequency of the read data. The k should be sufficiently large that most of the genome can be distinguished. For most eukaryotic … Web1.1.2 Counting k-mers in a genome In an actual genome or nished sequence, a k-mer and its reverse complement are not equivalent, hence using the -C switch does not make …
