I have obtained multiple bam files mapped with BWA. I wish to asses if the mapping of my reads was successful and will give me useful data for a ChIP-seq experiment. Because this is a pilot experiment, I have no technical duplicates, just the input and one file for each ChIP protein/histone modification.

I'm new to NGS and this is my first time with ChiP-seq data. I wish to have an overview about how the reads are distributed across the genome and about how the mapping qualities are distributed. I also wish to know about any additional measures I should look in this case to asses the usefulness of my data.

Do you know which Galaxy main tools I could use to make plots and get this overview about the data? Tutorials and additional hints are welcome.

If you are limited to Galaxy tools then this would not help but otherwise check out Qualimap.
