Hi

I have an experiment with 24 cel files divided into 6 groups (4 of each type). In affycoretools the group parameter would be like this: groups = rep(1:24, each = 4).

After the QC I found out that one of the arrays was really bad and had to be removed. In other words there are now 5 groups with 4 arrays and one with 3 arrays. What should I put in the group parameter now? I have tried different things but nothing has worked so far. 

Regards,
Ingrid
