在基因组学研究中，finish一个小的环形基因组，例如线粒体、叶绿体、质粒后，一般都会画一个全基因组的圈图，如下图：
最近我刚好在组装一个植物的细胞器，然后做了这个工作给大家推荐一个画圈图的工具OGDRAW。下面是作者网站上的相关介绍。
OrganellarGenomeDRAW is dedicated to convert genetic information stored in GenBank entries to graphical maps. The input text file has to be in GenBank flat file format, whereas the output format can be chosen among several formats. The application is especially optimized and adapted for the creation of high-quality, detailed circular maps of organellar genomes like the plastid genome (plastome) or the mitochondrial genome (chondriome). Nevertheless, you can upload any GenBank entry. The workflow is devided into three steps.
