Hello all, I noticed that Bioconductor provides cdf and probe libraries for the Affymetrix Gene Titan plates, but that the annotation libraries are either lacking or incomplete (Affymetrix control probes are missing). Consequently, I needed to create proper Affymetrix Gene Titan annotation libraries for Bioconductor myself. I share these with you on: http://nugo-r.bioinformatics.nl/NuGO_R.html I also updated the MBNI Custom CDF version 12.0.0 annotation libraries for the Gene Titan plates (same link).
