提取Operon的前序序列。在生物信息领域，处理微生物信息时，经常会要提取其操纵子的前序序列。由于操纵子的命名诡异，所以提取时经常较为困难。本程序以大肠杆菌为模式生物完成了此操作-Extract the pre-sequence of operons. In the field of bioinformatics, when processing with microbes, we often need to draw the pre-sequence of their operons. Due

用于生物信息中，多条序列进行聚类，做clustering，并在其过程当中画出有关的图形。-For bioinformatics, a plurality of sequences clustering, so clustering, and in the course of which to draw the pattern.
