来自宏基因组样本的连续序列的组装提出了一个特殊的挑战,因为存在多个物种,通常是密切相关的,在不同的丰度水平。捕获物种内的多样性,例如,病毒单倍型或细菌菌株水平的多样性,更具挑战性。我们提出MetaCortex,这是一个宏基因组组装器,它通过在底层组装图中搜索组装序列的局部变异特征并以序列图格式输出这些序列来捕获种内多样性。研究表明,与其他流行的宏基因组组装器相比,MetaCortex在具有高水平菌株多样性的模拟病毒群落和含有模拟菌株的模拟群落上产生准确的组装体,具有更高的基因组覆盖率和邻近性。源代码可以从https://github.com/SR-Martin/metacortex免费下载,用C语言实现,支持MacOS和Linux。本文给出的结果所使用的版本可在doi.org/10.5281/zenodo.7273627上获得。补充数据可在生物信息学网站获得。
The assembly of contiguous sequence from metagenomic samples presents a particular challenge, due to the presence of multiple species, often closely related, at varying levels of abundance. Capturing diversity within species, for example, viral haplotypes, or bacterial strain-level diversity, is even more challenging. We present MetaCortex, a metagenome assembler that captures intra-species diversity by searching for signatures of local variation along assembled sequences in the underlying assembly graph and outputting these sequences in sequence graph format. We show that MetaCortex produces accurate assemblies with higher genome coverage and contiguity than other popular metagenomic assemblers on mock viral communities with high levels of strain-level diversity and on simulated communities containing simulated strains. Source code is freely available to download from https://github.com/SR-Martin/metacortex, is implemented in C and supported on MacOS and Linux.
