    I have seen duplicate percentage of 33% in targeted high coverage experiment and based on my assessment of false positive and false negative I am happy not removing duplicates.

      It depends on what your experiment is. In some cases it has very little effect, in some it can be detrimental. In no case that I've heard of does leaving PCR duplicates in your data improve your results, however.

This method is not as good as deduping after mapping, but should be good enough. On the other hand, I do not think deduping is quite necessary for assembly.
        Why 14bp? Why not something else?

          Hi. everybody
          I have a problem about remove duplicates,
          In this study , http://www.ncbi.nlm.nih.gov/Traces/sra/?study=ERP000603
          It's have 2 Experiments, and 13 RUNs,
          How to do remove duplicates? by study? by Experiments? or by one runs?
          Thanks !!

            Remove PCR duplicates by library (and this looks like one big "library" mixed from 4 PCR pools). Optical duplicates are removed by lane (but I guess Picard would detect the within lane reads, given proper read group labelling).

              Advanced Sequencing Platforms Tackle Neuroscience’s Toughest Genomics Problems
              by SEQadmin2



              Genomics studies in neuroscience face a special challenge due to the brain’s complexity and scarcity of samples. Mapping changes in cell type and state using conventional next-generation sequencing methods remains challenging. Advances in technologies like single-cell sequencing, spatial transcriptomics, and long-read sequencing have opened the door to deeper studies of the brain and diseases like Alzheimer’s, amyotrophic lateral sclerosis (ALS), and schizophrenia.

              Cancer Drug Resistance: The Lingering Barrier to Rising Survival
              by SEQadmin2



              Cancer survival rates have significantly increased in the last few decades in the United States, reaching a combined 70% 5-year survival rate by 2021. Behind this number, there are years of research to find new therapies, drug targets, and early detection methods. But there is one core challenge that keeps slowing down these advances, and it’s about drug resistance.

              There is no single reason why many patients don’t respond to treatment as expected. Cancer is...
