It’s a very user-friendly (Galaxy-based) and helpful tool to test the quality of my ChIP-Seq datasets. Furthermore, the authors kindly helped to add a chicken reference genome not in their server before and continuously updated the tool’s functions after the paper has been published. For a beginner, I only suggest one thing to keep in mind: the publicly datasets the authors collected are mixed with different species, antibodies, and reads produced by different NGS platforms (e.g. Illumina GAII and HiSeq 2000). Based on my experience, the chicken with a smaller genome (~ 1.2GB), H3K27ac ChIP-Seq (strong histone modification antibody), and reads produced by Illumina HiSeq are easier to get a higher score compared to the mouse with a larger genome (~2.5 GB), p300 ChIP-Seq (weak transcription co-factor antibody, indirect binding DNA), and reads produced by GAII.
