Use of the exonmap infrastructure to analyse exon microrrays. A processing pipelines using exonmap and X:MAP software. The first steps (1-3) are similar to standard microarray analysis. Step 4 is specific for exonmap, and is a combination of filtering and mapping between genes, transcripts, exon and probesets using genomic annotations from X:MAP. Step 5 comprises gene visualizations (see Figures 3 and 4).
