  • length reads after trimming

    Hello!
    I have to trim primers of my reads, after trimming are there a length of reads suggest? So I would understand if I have to discard short reads. My analysis is on DNA.
    Thank you very much in advance

    You should discard reads too short to use for what you are doing. That said - you have not said what you are doing, or what length of reads you are starting with, so it's impossible to say. What is your read length, insert size distribution, and experiment?

      Thank you very much for your response. I am implementing my pipeline in order to analyse BRCA1 and BRCA2. The initial length of the reads is about 300bp, I don't know distribution of insert size, how I can find it?
      thank you in advance

        You can do insert size estimate by BBMap/BBMerge like this: http://seqanswers.com/forums/showpos...13&postcount=2

        That said for good libraries you should hardly have any adapter contamination. Why are you worried about short reads in a 300 bp run?

          Strategies for Sequencing Challenging Samples
          by seqadmin


          Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...
