Hi

I have some code which was working about a year ago. Now I have to re-use it and I get an error when running the following code:

fsa <- flowCore::read.flowSet(
    path = fcs_path,
    transformation = FALSE,
    phenoData = list(
      filename = "#SAMPLE",
      sample = "$SMNO",
      date = "$DATE",
      volume = "$VOL",
      proj = "$PROJ"
    )
  )

Error in parse_pd_for_read_fs(files, path, pattern, phenoData, sep, as.is,  : 
  Argument 'phenoData' must be of type 'AnnotatedDataFrame' or a filename
of a text file containing the phenotypic information

As I do not know much about flowcytometer and the file formats, I am completely at a loss what this error means. I understand it from the R side, but have no idea how I can solve it.

Also, I have no idea if this information is enough, or if more details are needed. If yes, please let ma know which ones and I can provide the info.

The data is from a BD Accuri C6 Plus. The Software is BD CSampler Plus Software Version 1.0.34.1.

Thanks a lot,

Rainer

Edit 1:

The following works:

fsa <- flowCore::read.flowSet(
    path = fcs_path,
    transformation = FALSE
)

We reworked on read.flowSet so that it focus on its main task (i.e. parse fcs files into flowSet) instead of doing too many things in one call, which complicates the code maintenance. So it no longer support a 'list' for phenoData argument.(I will update the doc to reflect this change). You can achieve the same goal by extracting the keywords from flowset and assign it to pData through the separate dedicated methods, e.g.

#read fcs
fcs.loc <- system.file("extdata",package="flowCore")
file.location <- paste(fcs.loc, dir(fcs.loc), sep="/")
fs <- read.flowSet(file.location[1:3])

#extract keyword list
kw <- keyword(fs, list("GUID", "SAMPLE ID"))

#assign it to pdata of fs
pData(fs) <- as.data.frame(kw)
pData(fs)
