A peak on FastQC graph Sequence Duplication Levels on MNase seq data
Good time to anyone! Here I have the result of MNase seq data analysis using FastQC. The problem is in this peak of duplicated sequences at the score >10. Its not good for data quality, I don't know why such a picture appear. If somebody've faced this problem before I will be very grateful to you for answer!

I am not familiar with MNase seq but it is normal to have a result like this depending on the context of the experiment. Please take a look at this blog post from authors of FastQC for alternate explanations, if this was not expected.

failin FastQC does not make the data bad. It all depends on type of data you are working with.
