WebWe can view the top 10 markers by average fold change across the two groups, for each cluster for a quick perusal: # Extract top 10 markers per cluster top10 <- conserved_markers %>% mutate(avg_fc = (ctrl_avg_log2FC + stim_avg_log2FC) /2) %>% group_by(cluster_id) %>% top_n(n = 10, wt = avg_fc) # Visualize top 10 markers per cluster View(top10) WebThe FindMarkers function allows to test for differential gene expression analysis specifically between 2 groups of cells, i.e. perform pairwise comparisons, eg between cells of cluster 0 vs cluster 2, or between cells annotated as T-cells and B-cells. First we can set the default cell identity to the cell types defined by SingleR: seu_int ...

WebJul 12, 2024 · DoHeatmap(object = obj, genes.use = genes), slim.col.label = TRUE, remove.key = T,group.label.rot = F, use.scaled = T) Is there a way to adjust the DoHeatmap command to rank the cells by the intensity of gene expression? Here's an example output: Web2 Answers. Sorted by: 1. If you are going to use idents like that, make sure that you have told the software what your default ident category is. This works for me, with the metadata column being called "group", and "endo" being one possible group there. Idents (combined.all) <- "group" endo_subset <- subset (combined.all, idents = c ("endo")) dxl filter objects

In your DoHeatmap () call, you do not provide features so the function does not know which genes/features to use for the heatmap. In your last function call, you are trying to group based on a continuous variable pct.1 whereas group_by expects a categorical variable. I understand a little bit more now.
