MEGAHIT: an ultra-fast single-node solution for large and complex metagenomics assembly via succinct de Bruijn graph
"V体育平台登录" Abstract
MEGAHIT is a NGS de novo assembler for assembling large and complex metagenomics data in a time- and cost-efficient manner. It finished assembling a soil metagenomics dataset with 252 Gbps in 44. 1 and 99. 6 h on a single computing node with and without a graphics processing unit, respectively. MEGAHIT assembles the data as a whole, i. e. no pre-processing like partitioning and normalization was needed. When compared with previous methods on assembling the soil data, MEGAHIT generated a three-time larger assembly, with longer contig N50 and average contig length; furthermore, 55 VSports手机版. 8% of the reads were aligned to the assembly, giving a fourfold improvement. .
