WebJan 20, 2024 · 由于Seurat heatmap(与DoHeatmap一起产生，如下图所示)，需要对heatmap中所有基因进行缩放，以确保高表达的基因不会在heatmap中占主导地位。为了确保我们在后面的热图中不会遗漏任何基因，我们将缩放所有基因。
WebSeurat can help you find markers that define clusters via differential expression. By default, it identifes positive and negative markers of a single cluster (specified in ident.1), compared to all other cells. FindAllMarkers automates this process for all clusters, but you can also test groups of clusters vs. each other, or against all cells.

WebDoHeatmap generates an expression heatmap for given cells and genes. In this case, we are plotting the top 20 markers (or all markers if less than 20) for each cluster. In [8]: top10 <- pbmc.markers %>% group_by ( cluster) %>% top_n (10, avg_logFC) Note: setting slim.col.label to TRUE will print just the cluster IDS instead of every cell name Webcluster1.markers <- FindMarkers(object = pbmc, ident.1 = 0, thresh.use = 0.25, test.use = "roc", only.pos = TRUE) VlnPlot(object = pbmc, features.plot = c("MS4A1", "CD79A")) # you can plot raw UMI counts as well VlnPlot(object = pbmc, features.plot = c("NKG7", "PF4"), use.raw = TRUE, y.log = TRUE)
