deseq2算法使用count值进行差异分析,标准代码如下: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 # 加载包library(DESeq2)library(stringr)# 加载数据 count矩阵load("draw_logFC.rda")mat[1:4,1:5]rowname<-str_split(rownames(mat),pattern="@",simplify=T,n=3)table(rowname[,3])rownames(...
def logfc_to_log2fc(logfc): return logfc / 1.xxx def log2fc_to_logfc(log2fc): return log2fc * 1.xxx ``` 在这段代码中,我们使用了常数1.xxx来进行logfc和log2fc之间的转换。这个常数的值是log2(10),因为logfc是以2为底的对数,而log2fc是以10为底的对数。 四、使用示例 下面我们来看...
甲基化信号值的差异分析也许不应该是看logFC 但是差异分析大家还是首先limma,而limma这个包本来是针对log后的表达矩阵设计的,这样的话,如果我们的输入是甲基化信号矩阵,实际上出来的结果是有问题的。 甲基化信号值的生物学意义 首先甲基化信号值通常是贝塔值,是介于0到1之间的连续变量。 公式计算:平均β=信号B /(...

它们仅仅是因为 |logFC| > [mean(|logFC|) + 2sd(|logFC|)] 公式而因地制宜的计算出来的,我无意中搜索这个公式确实发现了一个文献:《Identification of key genes unique to the luminal a and basal-like breast cancer subtypes via bioinformatic analysis》,链接是:wjso.biomedcentral.com/,它既然可以...

1.We might want to see the data structure a little differently(数据范围压缩了) 2.We might want to reduce skew to assist in modeling(更接近正态了) 3.We might want to straighten a nonlinear relationship in a scatterplot, so that we can model the relationship with simpler methods(更容易用...
Hello Seurat team, I'm using the "FindMarkers" function to calculate out the DEGs between two group of cells. The command line I wrote is : DEGs <- FindMarkers(obj, ident.1 = "ident1", ident.2 = "ident2", logfc.threshold = 0.25, verbose = FALSE). ...
In version 3.1.0 when I run FindMarkers or FindAllMarkers I get avglogFC values on the output file with infinity and -infinity values. code is good because Ive used it before, the same as always: Cluster6<- FindMarkers(Neo, assay = "RNA"...
