[BioC] problems with readIllumina()

[Ina Hoeschele]

Hi Karl and others,
   I am getting the same error message with the readIllumina function and the new beadarray package:

> setwd("C:/PHS_MESA_Epigenomics/5655508006")
> BLData.normexp = readIllumina(singleChannel=TRUE, useImages=FALSE, illuminaAnnotation="Humanv4", normalizeMethod="none", backgroundMethod="normexp")
Error in file(file, "rt") : cannot open the connection
In addition: Warning message:
In file(file, "rt") : cannot open file 'NA/NA': No such file or directory

When I was working with similar data 2 years ago I had to specify the array names like this:
readIllumina(textType=".txt", 
	arrayNames = c("4207121082_A_1","4207121082_A_2","4207121082_B_1",
	"4207121082_B_2","4207121082_C_1","4207121082_C_2","4207121082_D_1",
	"4207121082_D_2","4207121082_E_1","4207121082_E_2","4207121082_F_1",
	"4207121082_F_2"), singleChannel=TRUE, useImages=FALSE, 
	normalizeMethod="none", backgroundMethod="normexp")

Is this because I do not have a targets file? Do I get the error message because I did not specify the array names for 5655508006?

Above, I am trying to read the data on a single chip (5655508006) - how can I read data on multiple chips (that are in different sub-directories (5655508006, 5655508014, etc.)) with one call to readIllumina?

Many thanks for any help.

Ina

Hey,

I've been using beedarray quite often, but now with the new version I'm running in some error when trying to reading in the bead level data with readIllumina(). Does anyone know why this is happening or had a similar experience? What is meant with file 'NA/NA'?

Thanks for any help!
Karl
