  • ChIP-Seq Biological Replicates

    How are people handling biological replicates in ChIP-Seq experiments?

    I recognize the benefit of analyzing replicates independently, but what is the "best" way to then combine this data and end up with a single list of bound regions/peaks? As peak calls tend to vary by a few bases, a simple intersect of the data doesn't seem to be the best idea.

    However, combining the data pre-analysis concerns me also, as there is the (unlikely) possibility of a "strong" false peak in one dataset that may make its way through the analysis despite the fact that it doesn't exist in the replicate dataset...

    Hope that's clear -- if not, I'm happy to attempt to clarify my situation.

    Thanks!

    (In case it's not painfully obvious from my post, I am NOT a bioinformatician or programmer in any way...."just" a biologist who's not afraid of the command line. BTW, this site a great resource -- I've read nearly everything on this site and may have even understood some of it.)

    Strategies for Sequencing Challenging Samples
    by seqadmin


    Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...
