Hello,
I'm trying to create heatmaps based on genes within this GSEA gene set. There are a lot of genes in this set and I'm not expecting to have all of them on the heatmap.
When I run this code:
DoHeatmap(avgexp, features = alphavec, group.by = "ptorigin", angle = 90)
In which alphavec is the string vector of all genes in that gene set, I'm confronted with this error:
Error in DoHeatmap(avgexp, features = alphavec, group.by = "ptorigin", : No requested features found in the scale.data slot for the RNA assay.
I'm assuming this means that some genes were not found in my seurat object. However, how do I go about actually determining which genes are not present so I can remove them from the vector?
