MetaHIT "error-free" contigs from MetaBAT

We obtained this data from MetaHIT "error-free" contigs produced in Metabat [1]. The dataset was derived from raw read obtained obtained through 264 human gut sequencing runs conducted by the MetaHIT consortium [2]. The reads were mapped to 290 known genomes from the NCBI-database.To create the contigs, the reference genomes were shredded, resulting in 41 to 1617 contigs per genome. These contigs had 31 overlapping bases and lengths spanning 2.5K to 64.5K base pairs. The contigs are considered "error-free" as they were obtained directly from known genomes rather than being constructed fromby an assembly algorithm. We filtered contigs below 2.5k basepairs, resulting in a total of 177.146 contigs.See more in Metabat: https://bitbucket.org/berkeleylab/metabat/wiki/Home. <br>[1] Kang, Dongwan D., et al.

我们从MetaHIT项目通过Metabat工具生成的“无错误”重叠群（contigs）中获取了该数据[1]。该数据集来源于MetaHIT联盟开展的264次人类肠道测序运行得到的原始测序读段[2]。这些读段被映射到NCBI数据库中的290个已知基因组上。为构建重叠群，参考基因组被拆分，每个基因组产生41至1617个重叠群。这些重叠群具有31个重叠碱基，长度范围为2.5K至64.5K碱基对。由于这些重叠群直接来源于已知基因组，而非通过组装算法构建，因此被认为是“无错误”的。我们过滤掉了长度小于2.5k碱基对的重叠群，最终得到总计177.146个重叠群。更多信息请参见Metabat：https://bitbucket.org/berkeleylab/metabat/wiki/Home。<br>[1] Kang, Dongwan D., et al.
