Details

You can add additional cell metadata in two manners:

1. Provide a data.table or data.frame with gene annotations in the same order as the gene_ID column in fDataDT(gobject).

2. Provide a data.table or data.frame with gene annotations and specify which column contains the gene IDs. These gene IDs need to match with the gene_ID column in fDataDT(gobject).
