Mmm, did I not basically answer your question in this thread? A: how to generate CDF and before normalisation and after normlisation plot for Cla

Also, if you did some searching on (for example) this forum you would have learned that for the newest generation of Affymetrix arrays CDF files are not anymore provided (and used). see e.g. cdf file for Clariom S Human HT. The packages oligo or xps are the way to go to analyze these arrays!

What exactly is "RMA-Alt-splicing Normalisation"? Has it to do with the (non-Bioconductor) software 'AltAnalyze'? In any case, I am not familiar with both, but a quick glance at 'AltAnalyze' suggested to me that it makes use of Affymetrix Power Tools (APT), which uses the files than can be downloaded directly from Affymetrix (Thermo). Please realize that Affymetrix (also) does not provide CDFs for these newest arrays!
