[BioC] Limma time series analysis question

Dear all,

I am wondering what would be the optimal approach for limma to the
following setup:

I have an experiment repeated three times (A, B, C). Each repeat is
measured at five different time points (T1...T5) in three replicates

A T1 R1
A T1 R2
A T1 R3
A T2 R1

C T5 R1
C T5 R2
C T5 R3

Thus, A T1 is matched with A T2, T3, T4 and T5, but not with the B
series. So it is a mixed design.

I want to see genes that are differentially expressed relative to T1.
How do I do it correctly in limma?

Best regards,
