Hi all,

I want to test differential expression among (cond1+cond2)/2 and cond3. I
understand a contrast of (-0.5,-0.5,1)
will do this,  subsequently I should also be able to detect if  cond3 is
significantly close to (cond1+cond2)/2, cond1 or cond2.
I`m looking for a p-value for each of these comparisons, so I want to
classify my cond3 expression values into 3 groups

1 . cond1 like but not (cond1+cond2)/2 like.
2. (cond1+cond2)/2 like but not cond1 like and not cond2 like.
3. cond2 like but not  (cond1+cond2)/2 like.

Of course there will be cases where genes can outside these groups but
these 3 groups are what mainly interest me.
I hope I could explain, some guidance is greatly appreciated.

Thanks,
Al
