AggregateFlowFrames {FlowSOM} | R Documentation |
Aggregate multiple fcs files to analyze them simultaneously.
A new fcs file is written, which contains about cTotal
cells,
with ceiling(cTotal/nFiles)
cells from each file. Two new columns
are added: a column indicating the original file by index, and a noisy
version of this for better plotting opportunities (index plus or minus a
value between 0 and 0.1).
AggregateFlowFrames(fileNames, cTotal, writeOutput = FALSE, outputFile = "aggregate.fcs", writeMeta = FALSE)
fileNames |
Character vector containing full paths to the fcs files to aggregate |
cTotal |
Total number of cells to write to the output file |
writeOutput |
Whether to write the resulting flowframe to a file |
outputFile |
Full path to output file |
writeMeta |
If TRUE, files with the indices of the selected cells are generated |
This function does not return anything, but will write a file with
about cTotal
cells to outputFile
# Define filename fileName <- system.file("extdata","lymphocytes.fcs",package="FlowSOM") # This example will sample 2 times 500 cells. ff_new <- AggregateFlowFrames(c(fileName,fileName),1000)
