[BioC] error when running marrayNorm

Hi

Just to say I get this error message when my data has two many NA values in a particular print-tip area, or where too many of my data points are on the M = C * A line due to there being lots of divsion by 1.

Hi Yihuan,

I think you need to leave subset = TRUE.

You might find the function "maNorm" and maNormScale easier to use.

To do print-tip loess

data <- maNorm(faber.raw)

global loess

data <- maNorm(faber.raw, norm="l")

Cheers

Jean
