估计阅读时长: 8 分钟为了能够稳定的使用Ubuntu系统作为我的测试环境,我专门安装了Ubuntu的2404 LTS版本。但是发现虽然是LTS版本,仍然会因为系统更新而出现各种莫名奇妙的BUG。例如,在今天我为了安装软件,使用apt upgrade更新系统环境之后,出现了下面的消息: Order by Date Name Attachments ubuntu-24-04-noble-numbat • 66 kB • 198 click 2025年6月7日ti8S1 […]

哈哈,Thanks♪(・ω・)ノ
哈哈。这个R程序包用来做代谢组数据的biomarker分析确实挺方便的呢
This clarifies everything perfectly.
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.
