I have this GEO Illumina data GSE20159 that I need to analyze. This is an Illumina HumanHT-12 V3.0 expression beadchip. I work on Affymetrix-based microarray but this is the first time I am using Illumina data.
GSE20159 has GSE20159_non-normalized.txt.gz which contains only one GSE20159_non-normalized.txt. So how to process this file and get expression and how to do Background correction/normalization this data using neqc.
