Hi everyone,

I am working on 10X single-cell data. I created a seurat object following SCTransform pipeline. I wonder if it's possible to create a table using the Seurat object, which shows all the detected Genes, Cells, and UMIs. Then I plan to save this extracted table as a csv file for further works like filtering, sorting etc. It would be greatly appreciated if you could provide me with that code.

Thanks,
Volkan

To extract the data you can either access the object hierarchy or use the seurat function GetAssayData.

myData <- srtObject@assay$SCT@count

myData <- GetAssayData(object = srtObject, slot = "count")

You can chose between counts (unormalised), data (normalised), and scale.data (scaled), based on your needs. After, myData can be manipulated as a matrix or converted to data.frame (as.data.frame(myData)).

Have a look at the Data Access section of the seurat documentation

Thank you fracarb8 for your prompt reply. Finally, I created the table following your advice.
