I recently received some .bigwig files from a chipseq experiment. I loaded the files into IGV.
The interpretation is rather intuitive.
My question is the following: What exactly do the track heights represent?
For IgG control, the track height is low ranging from 0~5.
For positive controls, such as H3K4me3, I see clear peaks with height ~100.
Do track heights simply mean the number of reads mapped to that genomic interval during peak calling? Does it literally mean there are ~100 reads that aligned to that region in the H3K4me3 .bam file?
Thanks so much.
