估计阅读时长: 11 分钟给定一组n个字符串数组,找到包含给定集合中每个字符串的最小字符串作为子字符串。我们可以假设这个字符串数组中没有字符串是另一个字符串的子字符串。那么基于上面的描述,我们就可以得到下面所示的问题求解目标: let arr[] = ["catg", "ctaagt", "gcta", "ttca", "atgcatc"] // output: gctaagttcatgcatc 上面的问题描述实际上是一个最短超字符串问题(shortest common superstring) Order […]

其实,你不应该直接跑原始表达矩阵的。因为在原始表达矩阵中,基因的特征数量可能会非常多,做随机森林或者SVM建模就会会非常久。应该先用limma程序包对矩阵筛选一次,例如用log2fc绝对值按照阈值cutoff筛选一次,或者对log2fc绝对值排序后取前1000个特征,得到小一些feature集合的矩阵后再使用这个程序包做机器学习分析。
Thanks for taking the time to create this.
就是随便看看!
c⌒っ゚Д゚)っ救命啊,谢老师,我试了下用这个程序包直接跑转录组矩阵,跑了好久都没有结果
Could you provide some practical examples of how this R package is used? For instance, how does it perform when…
