perform "str(metadata(sce.Pollen)$ssc$variable.gene$sd) " got "NULL"

Hi, Japrini
I am a fresh man of R language . And i performed the codes following your guide, but i got
NULL instead of chr [1:1500] "G5596" "G945" "G244" "G496" "G3558" "G5598" "G1909..." when i visualize the variable gene selection in part:

sce.Pollen <- ssc.variableGene(sce.Pollen,method="sd",sd.n=1500) str(metadata(sce.Pollen)$ssc$variable.gene$sd)

Could you give me some suggestions？ Thanka a lot!

Hi, dreamlovesft,

I think the problem is that in the recent implementation, variable genes are not stored in metadata(sce.Pollen) any more. Instead, you can find variable gene in rowData(sce.Pollen). I should re-compile the vignette. Sorry for the inconvinience!

Best Regards
