Dear Bioconductor community,

I have read historical posts with the same problem but no solution has been posted to date. The contact provided in the ABarray vignette is out of date.

I am using the ABarray to process an Applied Biosystems GSE dataset using the human genome survey microarray version 2 platform.

I have checked that there are no differences in the sample names entered in the Data File and Experiment Design files (there are no differences) and I have named the respective columns according to the conventions described in the vignette.

it returns the following error while doing the basic analysis on non-normalised data using the 'ABarray' function. I have given the script below with the error:

Reading data from GSE_raw_data.csv ......
    This may take several minutes....
Finished data reading.
The results will be in the folder: Result_stage/

Perform basic analysis for non-normalized data ...
