Hi all,

I'm analysing some microarray data and just calculated p-values using a t-test between 2 conditions (each with 3 replicates; total number of genes 14000). My p-values and adjusted p-values are coming out exactly the same. I've tried both FDR and bonferroni for correction using the p.adjust function in R and the results are the same. Is it possible to have the exact same p-values and adjusted p-values. I'm getting a bit doubtful. Any thoughts.

Thanks!!!
