Chip seq peak
WebThe analysis for ChIP-seq data is to predict the regions of the genome where the ChIPed protein is bound by finding regions with peaks. A fine balance between sensitivity and specificity depends on choosing an appropriate peak-calling algorithm and normalization method based on the type of protein ChIPed. http://guertinlab.cam.uchc.edu/meds5420_2024/230306_Lec14_MACS.html
