Default How to adjust the p values of edgeR?

Hi every one,

I am trying adjust the p values of my two-treatment comparison by edgeR. I am not sure if FDR need to be calculated with topTags before the adjustion, because exactTest just gives the p values without FDR.

In addition, how can I extract the DE genes with padjusted <= 0.05 from the following dataframe.

logFC logCPM PValue FDR padjusted
