datasets in scRNAseq can't be retrived for reference mapping

[tufeiyinjie]

Hi,

I tried to leverage the singleR package to add the annotation to data. Instead of using the built-in data, I want to use HeOrganAtlasData (including different human organs) for reference mapping, because my data was human liver. listDatasets() function returns the datasets, including HeOrganAtlasData. However, when I run HeOrganAtlasData(), it can't be retrieved. Could you give me a hint to fix that?

Thanks, Fei
