[BioC] cellHTS Repeat Values in Text Output

Hi,

I am seeing a problem with the text output in my multi-channel experiment. I have different types of data so I want to normalize and score the channels separately. Therefore, I do not want to run summarizeReplicates. I think the following will show what I am doing:

x <- readPlateList("Platelist.txt", name=experimentName, path=dataPath)
x <- configure(x, "Description.txt", "Plateconf.txt", "Screenlog.txt",
               path=dataPath) 
xn <- normalizePlates(x, scale="multiplicative", method="median", 
                      varianceAdjust="none")
xsc <- scoreReplicates(xn, sign="-", method="zscore") 
xsc at state[3]=TRUE
getTopTable(cellHTSlist=list("raw"=x,"normalized"=xn, "scored"=xsc),
            file="testtable.txt")

The output in testtable.txt (and similarly in writeReport's text output) has repeated values that are not what is actually in the cellHTS objects.

Is it ok to force the scored state of xsc to TRUE? Please let me know if I'm using this correctly. I really appreciate your prior quick and helpful responses.

thank you,
