I would like to hear your opinion to the results of my Whole-Genome-Sequencing (WGS) I did with samples from a S. cerevisiae strain.
After mapping the samples with
bwa, marking duplicate (
Picard) and doing variant calling (
bcftools) and CNV discovery (
CNVpytor) I have plotted the results and got a strange behavior of my results.
The mapping looks very consistent and the mapping results are >99% with good quality. But somehow I haven't seen this kind of mapping before. It looks like a parabel, but for all the sequences (s. attached image).
CAn anyone explain this behavior? I am not sure how to interpret this results
