Annotate observations in a FCS file with cluster assignment
1 | SPADE.addClusterToFCS(infilename, outfilename, clusterfilename, cols = NULL, arcsinh_cofactor=NULL, transforms=flowCore::arcsinhTransform(a=0, b=0.2), comp=TRUE)
|
infilename |
Name of input FCS file |
outfilename |
Name of output FCS file |
clusterfilename |
Name of FCS file with subset of cells used in clustering |
cols |
Usually a vector of strings specifying the columns to be used in the density calculation, e.g., c("(Cd110)D","(Cs111)D"). Strings will be matched against the parameter names extracted from the FCS file. The default=NULL will use all parameters. |
arcsinh_cofactor |
DEPRECATED. Cofactor used in arcsinh transform |
transforms |
Transform object to apply to data. A single transform object will be applied to all channels. To apply different transforms to specific channels use a named vector of transform objects (where names are parameter names). |
comp |
Apply compensation matrix if present in SPILL or SPILLOVER keywords |
The name of the written file is returned.
Underlying implementations have been parallelized with OpenMP. Set
OMP_NUM_THREADS
in environment to control the number of threads used.
