Hi Harris,

You need to contact the sequencing center that ran your samples to get the
fragment length. Nobody here will be able to answer that question.

As for the FDR, that depends on what you are talking about. You can compute
the FDR for the peak detection, our you can compute the FDR from a
comparison between sample types, in which case you will be using different
samples.

Best,

Jim
