Hi, I'm using Control-FREEC to identify CNVs. After installing I've used a sample data whose CNV profile looks like the figure below (link provided) where pink represents copy number gain and green represents loss. I don't how how to interpret this kind of CNV profile and what does each dots represents and why there is a line below just above the X-axis? Could anybody explain regarding this? https://ibb.co/VqDddf2

The job is not fully done yet. You need the direct link to the image, not the link to the webpage that has the image embedded (which is what you have used here)
Please carefully read the post I linked to and use it well.
I have not worked with freec but for me your sample looks qc failed
Agreed, this looks crazy messy. What sort of data is this? Exome, wgs? I've never used Control-FREEC, but it doesn't look like segmentation is being performed either.
This WES data and ControlFC does segmentation itself. But still that data looks so noisy. That's why can't interpret it. I've used sorted BAM files (created using GATK best practice pipeline) as an input for ControlFC.
Have you done QC on the WES data? This looks like a potential quality issue.
