The taxonomic classification of viral sequences is frequently used for the rapid identification of pathogens, which is a key point for when a viral outbreak occurs. Both Oxford Nanopore Technologies (ONT) MinION and the Illumina (NGS) technology provide efficient methods to detect viral pathogens. Despite the availability of many strategies and software, matching them can be a very tedious and time-consuming task. As a result, we developed PIMGAVir and Vir-MinION, two metagenomics pipelines that automatically provide the user with a complete baseline analysis. The PIMGAVir and Vir-MinION pipelines work on 2nd and 3rd generation data, respectively, and provide the user with a taxonomic classification of the reads through three strategies: assembly-based, read-based, and clustering-based. The pipelines supply the scientist with comprehensive results in graphical and textual format for future analyses. Finally, the pipelines equip the user with a stand-alone platform with dedicated and various viral databases, which is a requirement for working in field conditions without internet connection.
病毒序列的分类学分类常用于快速鉴定病原体,这是病毒爆发时的关键点。牛津纳米孔技术(ONT)的 MinION 和 Illumina(NGS)技术都提供了检测病毒病原体的有效方法。尽管有许多策略和软件可用,但将它们匹配可能是一项非常繁琐和耗时的任务。因此,我们开发了 PIMGAVir 和 Vir-MinION 这两个宏基因组分析管道,它们可以自动为用户提供完整的基线分析。PIMGAVir 和 Vir-MinION 管道分别适用于第二代和第三代数据,并通过三种策略为用户提供读段的分类学分类:基于组装、基于读段和基于聚类。这些管道以图形和文本格式为科学家提供全面的结果,以供未来分析使用。最后,这些管道为用户提供了一个带有专用和各种病毒数据库的独立平台,这是在没有互联网连接的野外条件下工作的要求。
