Webmarker genes some <- findMarkers (vsd mat, groups=sample info$Cell type, test.type="wilcox", pval.type="some") marker genes any <- findMarkers (vsd mat, groups=sample info$Cell type, test.type="wilcox", pval.type="any") but this doesn´t improve the results either. Do you know what could be going wrong? WebThe FindAllMarkers () function has three important arguments which provide thresholds for determining whether a gene is a marker: logfc.threshold: minimum log2 foldchange for average expression of gene in cluster relative to the average expression in all other clusters combined. Default is 0.25. Cons:

WebThe Wilcoxon Rank Sum test (aka Mann-Whitney) works with unequal sample sizes. The original paper (referenced below) did some analyses with different sample sizes and showed its consistency and asymptotic normality (see table I, n = 8 on page 54). They also go on to show its robustness for small sample sizes. WebHi all, I am approaching the analysis of single-cell RNA-seq data. I have seen that Seurat package offers the option in FindMarkers (or also with the function DESeq2DETest) to use DESeq2 to analyze differential expression in two group of cells..
