clustering based on most significant pvalues does not separate the groups!
Hi all,
I have some microarray data on 40 samples that fall into two groups. I have
a value for 480k probes for each of those samples. I performed a t test
(rowttests) on each row(giving the indices of the columns for each group)
then used p.adjust() to adjust the pvalues for the number of tests
performed. I then selected only the probes with adj-p.value<=0.05. I end up
with roughly 2000
