| Data processing |
Probesets flagged as cross-hybridizing were removed. Probesets were assigned to genes based on the GENCODE v10 annotation (July 2011). To normalize, we first classified each exon as constitutive, meaning present in all annotated isoforms, or not constitutive for each gene, reasoning these would be the most robust across celltypes. For genes with at least 4 constitutive probesets, only constitutive probesets were used to normalize. For all other genes, including all non-protein-coding genes, we sused all probesets that mapped to the gene. To normalize, we used Affymetrix Power Tools (APT) with the chipstream command “rma-bg, med-norm, pm-gcbg, med-polish”. This chipstream calls for an RMA normalization with gc-background correction using antigenomic background probes. We used an ComBat to correct for batch effects.
