Per base sequence content of FastQC Report

Hello,

I have result of RNA sequencing FastQC Report.

It was failed in Per base sequence content, but passed Adapter Content.

I went to https://sequencing.qcfail.com/articles/positional-sequence-bias-in-random-primed-libraries/.

It seems the primers problems.

How I can fix this?

Thanks in advance for great help!

Appears that my answer from yesterday was lost during the cut-over to the new biostars codebase. Basically, there is nothing to fix here as the linked blog post concludes. The data should align well.

it could not be a problem, the recent library preparation uses a transposase system that generates that pattern on the first bases, check what kit was used.
