Bowtie比对结果进行聚类，然后该程序完成提取聚类中与基因组错配碱基位点的A、T、C、G碱基的覆盖情况-Bowtie than clustering the results, and then extract the clustering process is complete mismatch with the genomic base sites A, T, C, G bases coverage

根据已知A-to-I RNA编辑位点，查找bowtie比对结果进行聚类后的编辑位点碱基覆盖情况-According to the known A-to-I RNA editing sites, find bowtie than the results after the editing site cluster base coverage
