Microsatellite loci comprise an important part of eukaryotic genomes. Their applications in biology as genetic markers are related to numerous fields ranging from paternity analyses to construction of genetic maps and linkage to human disease. Existing software solutions which offer pattern discovery algorithms for the correct identification and downstream analysis of microsatellites are scarce and are proving to be inefficient to analyze large, exponentially increasing, sequenced genomes. Moreover, such analyses can be very difficult for bioinformatically inexperienced biologists. In this paper we present Microsatellite Genome Analysis (MiGA) software for the detection of all microsatellite loci in genomic data through a user friendly interface. The algorithm searches exhaustively and rapidly for most microsatellites. Contrary to other applications, MiGA takes into consideration the following three most important aspects: the efficiency of the algorithm, the usability of the software and the plethora of offered summary statistics. All of the above, help biologists to obtain basic quantitative and qualitative information regarding the presence of microsatellites in genomic data as well as downstream processes, such as selection of specific microsatellite loci for primer design and comparative genome analysis.
微卫星位点是真核生物基因组的重要组成部分。它们在生物学中的应用作为遗传标记与众多领域相关,从亲子关系分析到遗传图谱的构建以及与人类疾病的连锁。现有的提供模式发现算法的软件解决方案很少,并且对于分析大型、指数增长的测序基因组来说效率低下。此外,对于没有生物信息学经验的生物学家来说,这样的分析可能非常困难。在本文中,我们提出了微卫星基因组分析(MiGA)软件,通过用户友好的界面在基因组数据中检测所有微卫星位点。该算法通过用户友好的界面,通过全面而快速的搜索来寻找大多数微卫星。与其他应用程序不同,MiGA 考虑了以下三个最重要的方面:算法的效率、软件的可用性以及大量提供的汇总统计信息。所有这些都帮助生物学家获得关于基因组数据中微卫星存在的基本定量和定性信息,以及下游过程,例如为引物设计和比较基因组分析选择特定的微卫星位点。
