Hello,

I am trying to run ChIPQC on 3 experimental samples and 1 control sample. When I run ChIPQC I get an error message when ChIPQC tries to analyze the 3rd scaffold. Here is the ChIPQC command I ran and the corresponding output.

> Experiment_ChIPQC <- ChIPQC(ExperimentTable, chromosomes = NULL)
Sample1     NA bed
Sample2     NA bed
Sample3     NA bed
