"SCT is not an assay present in the given object" even though it is present

[viktorfeketa]

When running Azimuth while specifying assay = "SCT"

I am getting an error: Error in GetAssay.Seurat(object = object, assay = assay) : SCT is not an assay present in the given object. Available assays are: RNA

even though the query Seurat object clearly contains the "SCT" assay

I am using a custom-made Azimuth reference produced from a public dataset using AzimuthReference() with specifying: refAssay = "SCT" so the reference assay should also contain the SCT assay

Can you include the output of query@assays ?

sure, here it is:

I think the topic starter should have just used the integrated assay and it would have probably solved his issue...
