Reannotation of the platforms identified several classes of transcripts, most of them being probes representing protein-coding transcripts from Gencode. In addition, we found more than 10,000 non-protein-coding transcripts from the Noncode, LNCipedia, and MiTranscriptome databases (Figure 4.2).
Analyzing the proportion of transcript classes in each platform (Figure 4.3), a great variability can be seen both in the total amount and in the proportion of transcript classes found in each platform.
