I am trying to analyze a RNA seq, single end SRA dataset. For this do i have to perform Markduplicates as it was mentioned in the tutorial bellow. When i do so, I am seeing 70-80% duplicates.In the example provided in the tutorial, it was less than 10% for paired end data.I am wondering if I should perform markduplicate, considering it is a single end data.Please advice. Do i have to do anything different considering micro RNA sequencing data as compared to tutorial.

Thank you.

I would suggest skipping this step in the analysis but you should also consider advice from sources with a specific focus on this type of analysis (publications, and possibly general bioinformatics forums like
