Hi there,

I am trying to get the gene name using this code

libreNameEnsembl <- as.matrix(cds@rowRanges@elementMetadata@listData$gene_short_name)
GeneNameSymbol <- AnnotationDbi::select(org.Mm.eg.db, keys=GeneNameEnsembl, columns='SYMBOL', keytype='ENSEMBL')

but I keep getting this error:

Error in .testForValidKeys(x, keys, keytype, fks) : 
  object 'GeneNameEnsembl' not found
