I've successfully run ChipQC on my samples and all plots generated. The report is empty though. A file is created called 'ChiP QC report' except nothing is in it.

My code is:

E2F7 = ChIPQC(E2F_sampleSheet, annotation = "hg19")
ChIPQCreport(E2F7, reportName="ChIP QC report: E2F7 and E2F8", reportFolder="ChIPQCreport")

any ideas on why the report is empty?

Thanks in advance.
