    count reads number in collapsed file

    Hi all,

    I used bowtie to align a collapsed fasta file to the bovine genome and get a fasta file (mapped.fa) including all the mapped reads. But this mapped.fa is also a collapsed file. So how could I get the total reads number in mapped.fa, instead of the unique reads number?

    Thanks.

    What do you mean by "collapsed"? Could you copy and paste the exact commands that were run?

      Hi Heisman, thanks for your reply. The collapsed file included the unique reads:

      >1-30176523
      TCAGTGCACTACAGAACTTTGT
      >2-17234938
      TTCAAGTAATCCAGGATAGGCT
      >5-10273189
      TACCCTGTAGAACCGAATTTGT
      >6-10202799
      TGAGATGAAGCACTGTAGCT
      >7-7833696
      TGAGATGAAGCACTGTAGCTCT
      >8-7677783
      TGTAAACATCCTCGACTGGA
      >9-7403197
      TGTAAACATCCTCGACTGGAAGCT
      >10-5760993
      TGGGGGGCCCAAGTCCTTCTGATCGAGGCC

      So here I can get the number of total unique reads. But each unique read represents thousands of reads. How could I get the total number of the redundant reads in this file?

      Thanks!

        From Collection to Sequencing: Why Sample Preparation and Preservation Define Sequencing Data
        by SEQadmin2


        Data variability is still an issue in sequencing technologies despite the advances in reproducibility and accuracy of these platforms. But the problem does not originate in the sequencing itself, but in the previous steps, before the sample reaches the sequencer.


        The first step is collection, followed by preservation and sample preparation for analysis. Most scientists overlook those steps, but not being careful might just be skewing the experiment’s results.

        Environmental Genomics in the Age of NGS: From Microbes to Conservation Strategies
        by SEQadmin2

        Studying ecosystems means dealing with complex, multi-species communities that are hard to observe at scale. This complexity, however, hides many important questions to be answered, from how biogeochemical cycles work and how climate change can affect species distribution to how conservation strategies can work best.


        Genomics, particularly since the expansion of NGS, has transformed ecosystem ecology. By sequencing environmental DNA, we can now assess biodiversity without direct...
