reset 'Original_ID' column in a flowframe — resetCellIDs • CytoPipeline

: on a flowCore::flowFrame, reset '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 replaces the existing IDs by the user provided ones. If not, an appendCellID() is called.

resetCellIDs(ff, eventIDs = seq_len(flowCore::nrow(ff)))

Arguments

ff: a flowCore::flowFrame
eventIDs: an integer vector containing the values to be set in expression matrix, as Original ID's.

Value

new flowCore::flowFrame containing the amended (or added) 'Original_ID' column

Examples


data(OMIP021Samples)

ff <- appendCellID(OMIP021Samples[[1]])

subsample_ff <- subsample(ff, 100, keepOriginalCellIDs = TRUE)

# re-create a sequence of IDs, ignoring the ones before subsampling
reset_ff <- resetCellIDs(subsample_ff)
