cluster0_conserved_markers <- FindConservedMarkers(seurat_integrated, ident.1 = 0, grouping.var = "sample", only.pos = TRUE, logfc.threshold = 0.25) FindConservedMarkers()函数的输出是一个矩阵,其中包含按我们指定的簇的基因 ID 列出的推定标记的排名列表,以及相关的统计数据。请注意,为每个组(在我...
运行命令: cluster0_conserved_markers <- FindConservedMarkers(seurat_integrated, ident.1 = 0, grouping.var = "sample", only.pos = TRUE, logfc.threshold = 0.25) Error: Please install the metap package to use FindConservedMarkers. This can be accomplished with the following commands: --- ins...
大概就是说FindMarkers()是指定的两个组之间的差异基因;FindAllMarkers()是一个组和剩下其他组的差异基因,是最常用的;FindConservedMarkers()其实是在单细胞分析中,有两个处理组 'g1' 和 'g2' ,而 'g1' 和 'g2' 组中又恰好有相同的细胞亚群 0 和 1,求在 'g1' 中细胞亚群 0 和细胞亚群 1 的差...
而FindConservedMarkers()用来找群体细胞的Marker gene。 b.interferon.response <- FindMarkers(immune.combined, ident.1 = "B_STIM", ident.2 = "B_CTRL", verbose = FALSE)nk.markers <- FindConservedMarkers(immune.combined, ident.1 = 6, grouping.var = "stim", verbose = FALSE)head(nk.markers...
Dear Seurat team, I updated the Seurat package to version 4.2.0 and noticed that the results by FindMarkers and FindAllMarkers were different than ones generated by Seurat v4.1.0. I loaded the old Rds file generated by Seurat v4.1.0 and ...
FindConservedMarkers(seurat_integrated, ident.1 = cluster, grouping.var = "sample", only.pos = TRUE, min.diff.pct = 0.25, min.pct = 0.25, logfc.threshold = 0.25) 您将认识到我们之前为FindAllMarkers()函数描述的一些参数;这是因为它在内部使用该函数首先在每个组中查找标记。在这里,我们列出了使...
在seurat中,如果运行了RunUMAP或者RunTSNE后自动分群后,FindAllMarkers和FindMarkers基本就是一样的;如果没有进行RunUMAP或者RunTSNE分群,那么需要先运行BuildClusterTree(object)函数,利用树聚类先分群 FindAllMarkers and FindMarkers 示例: 首先加载数据 pbmc.data<-read.csv("GSE117988_raw.expMatrix_PBMC.csv",he...
