Hi

Are all your input p values the same? If so your output FDR values would be the same.

Or are all your p-values relatively large? Then (nearly) all your FDR values might be 1.

Why don't you put a small example up of what you did? Then we could see what method you used etc.

Regards

Dear All,

It is not a typical R question (though I use R for this) but I thought
someone will help me. For the list of P values, I have calculated FDR
using p.adjust() in R (bioconductor). But my FDR values are same for all
the P values. When do we get same FDR values? Does the smallest P values
should less than 1/N? (where N is the number of P values)

Thanks in advance.

Kind regards,
Ezhil
