### Next Steps **Next Steps**  The workshop has performed some novel analyses, this is a preliminary work. It's clear the estimate of transcript initiation has a tremendous amount of uncertainty associated with it. Microarray probe sets are not distinctly comparable with each other as the specific sequences of the probes vary in their target affinity.   Within the cell processes abound that can all affect the actual amount of protein produced compared to the mRNA reported by a microarray. Just a few of these may include nonsense mediated decay, inhibitory RNA, post-translational editing, protein sorting amongst cellular compartments, secondary structure in the mRNA.
