Scale.data not found in Seurat object

[anushasjoshi]

I am trying to generate a heatmap from the plot_heatmap function but I am running into this error of ERROR in rownames(dataset@assays$integrated@scale.data): "Trying to get slot "scale.data" from an object of a basic class ("NULL") with no slots, although there is a slot named scale.data in my seurat object. How can I solve this issue?

I have the same issue..

Hi @Zhongqige - Same issue, because my Seurat object is not an integrated object. It is just a simple merge of different sample. So there will not be an Integrated Assay for the Seurat object.

not sure if I understand you correctly, but one of the fixes is to run this before plot_heatmap: " seurat_obj@assays$integrated <- seurat_obj@assays$SCT
"
