The bigger problem is what to say in the Discussion section. Right now it's a shambles, with lots of interesting points and good sentences and well-written paragraphs all jumbled together. I need to get a better perspective on this - to think about what actually should be discussed.
One place to start is the Introduction. Issues we raised there should be addressed and ideally resolved in the Discussion. Unfortunately, our lovely work doesn't really resolve these.
Well, so much for working on the Discussion... I'm now back to asking myself (and, in absentia, the postdoc) questions about how we interpret his analysis of interaction effects: Do interaction effects explain the discrepancy between genomic motif and uptake motif? Do interaction effects support the hypothesis that uptake bias is intrinsic to the mechanism of uptake, and not the effect of a single dedicated recognition protein? And more questions I've added to his lovely figure, so I remember to ask him them tomorrow.
And now, I've got two manuscript reviews (both overdue) and a book review to do.
