-
- Nice and ‘gentle’ introduction to ChIP-seq data analysis -
Example of data analysis workflow (subjective) - No deep details about the pros and cons of tools - Notes on reproducibility and repeatability - Do’s and don’ts of ChIP data analysis (qc, IDR, duplicates reads ,normalisation etc ..) -
- Published during the ENOCDE media hype - Epigenomics flavored
paper - Focus on DNase HS and Open Chromatine region - Details about the usage of ChIP technology (use case) - Histone modifications and TFBS to explore the DHS - Example of Data integrations in action -
- Guide to ChIP-seq pipeline development - Details about ‘details’
and focus on adapting the tools to the data analyzed - Tools/Seeds mini-benchmarking : example bwa/novoalign - Post analysis data exploration (annotation, visualization, filtering ..) - Irreproducible Discovery Rate .. again -
- Nice overview of using both technologies to answer specific
questions - Explaining the peak calling algorithms - Review of the models used by peak callers - More focused on peak calling than the details about other parts of the ChIP- seq data analysis modules -
