Seurat Violin Plot: Why do dots align in one row? I am analyzing a rather small scRNAseq dataset (39797 features across 3522 samples) and I have observed that dots in the violin plot are plotted in one line next to each other rather than in a cloud of dots (see plot below):

I am just wonndering what the reason might be for this?
I have followed the Integration and Label Transfer tutorial using SCTransform (https://satijalab.org/seurat/v3.1/integration.html). After the integration process I switched back to the SCT assay, which should contain the normalized counts. For plotting I used the following command:
VlnPlot(..., assay = &quot;SCT&quot;, slot = &quot;data&quot;), again specifying to use the normalized counts.
Can someone explain me why this is the case?
Thank you already in advance!
That is because SCTransform (mostly) outputs discrete values, you can check the @slot of your Seurat object.
