WebHandling replicates in ChIP-seq As with any high-throughput experiment, a single assay is often subject to a substantial amount of variability. Thus, it is highly recommended to setup your experimental design with a minimum of 2-3 biological replicates. Web4 Preparation of the ChIP-seq and control samples: read extension The reads correspond to sequences at the end of each IP-ed fragment (single-end sequencing data). As discussed in the lecture, we need to extend them to represent each IP-ed DNA fragment. We estimate the mean read length using the estimate.mean.fraglen function from chipseq ...
