基本模式：利用CMap将差异基因列表与数据库参考数据集比对；根据差异表达基因在参考基因表达谱富集情况得到一个相关性分数（-100~100）；正数表示上调和下调的差异表达基因与参考基因表达谱具有相似性；负数表示上调和下调的差异表达基因与参考基因表达谱可能是相反的；最终，根据参考基因表达谱相关性分数排序。
肿瘤药物筛选使用：
A total of 300 DEGs with the most significant fold changes (150 DEGs（单个列表输入上限150个） upregulated and 150 DEGs downregulated in the HMC4 cluster) were entered into the Connectivity Map database following the instructions provided by the website. In this study, the enrichment score generated by Connectivity Map analysis was set to < − 97（肿瘤中以< − 97筛选分子靶点）；and < − 95 （筛选化学药物）for the significant threshold of molecular targets and chemical compounds, respectively.
一般首先查看是否有相关性大于95%和小于-95%；如果没有，可以适当放宽范围到90%（肿瘤就选择负相关呗）
