[BioC] ABarray error

[Mani, Jay]

Hi ,

I am trying to use a applied biosystems dataset using human genome survey microarray version 2 platform. I tried using the ABarray package and it gives me an error while doing the basic analysis on non-normalised data. I have given the script below with the error. 

Reading data from C:/Users/jay/Desktop/rawdata/_raw_data_modified.txt ......
    This may take several minutes....
Finished data reading.
The results will be in the folder: Result_Status/ 
[1] "Creating plot for Signal Hybridization_Control ..."
[1] "Creating plot for Signal Negative_Control ..."
[1] "Creating plot for Signal IVT_Kit_Control_BIOB ..."
[1] "Creating plot for Signal IVT_Kit_Control_BIOC ..."
[1] "Creating plot for Signal IVT_Kit_Control_BIOD ..."
[1] "Creating plot for Signal RT_Kit_Control_DAP ..."
[1] "Creating plot for Signal RT_Kit_Control_LYS ..."
[1] "Creating plot for Signal RT_Kit_Control_PHE ..."

Perform basic analysis for non-normalized data ...
[1] "Creating barplot for probes detectable ... QC_DetectableProbeSN3"
Error in is.null(x) || all.equal(x, y, check.attr = FALSE) : 
  invalid 'y' type in 'x || y'


                      I have checked if the sample names in the data file match with the design file and all of them do. I am stuck at this point. It would be great if someone could me solve this issue

Thanks


Jay

The best resource that we have is the vignette for the BeadArrayUseCases
pacakge. It accompanies our paper that came out in PLoS one 'BeadArray
Expression Analysis Using Bioconductor'
