: on a flowCore::flowFrame, append a 'Original_ID' column. This column can be used in plots comparing the events pre and post gating. If the 'Original_ID' column already exists, the function does nothing
appendCellID(ff, eventIDs = seq_len(flowCore::nrow(ff)))
a flowCore::flowFrame
an integer vector containing the values to be added in expression matrix, as Original ID's.
new flowCore::flowFrame containing the added 'Original_ID' column
data(OMIP021Samples)
retFF <- appendCellID(OMIP021Samples[[1]])
