  • Confusing about definition of singleton in transcriptome assembly

    Hi all,
    I am working about denovo assembly of non-model organism by Trinity assembler but i still confusing of definition's "singleton".

    Definition 1: Some papers and journals define singleton: TGICL cluster contig(transcripts) from Trinity's output and we have 2 class is "Cluster" and "Singleton". (http://www.plosone.org/article/info%...l.pone.0014233)

    Definition 2: But when i read some website or blog i realize singleton is reads which do not overlap with other reads in assembly process

    So which 's definition right? and if "definition 2" 's right, how to extract "non-overlap reads" from Trinity's output (transcripts)

    Thanks in advance.

    Hello,

    Please see this link :- http://seqanswers.com/forums/showthread.php?t=46711. Well I was also very much confused about singleton. As rick mentioned in this post that align reads without mate(pair) reads are known as singletons. I am agree with him. But 72,424 singletons in this plos one paper, make me curious to known more about singletons.

    Thanks,
    Reema,

      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...
