  • SOAP vs Bowtie output

    Hello all,

    When I perform a SOAP and a Bowtie on my data (single reads) and map these reads against my reference sequence (using Sequencher), I get quite different results. When using SOAP, the reads align in blocks against the reference sequence; while for Bowtie, I get a much more equal distribution of the reads (see attachments). I used different parameters for both, but I always get the same results.

    Do you experience the same?
    What could be the cause of this (bioinformatics or non-bioinformatics)?

    Any help more than welcome,

    Thanks,

    Steven

    Nobody using SOAP neither Bowtie...??

      Can maybe somebody say how their results look like? Blocks or a continuous stretch of reads?

      Many thanks

        Perhaps nobody uses Sequencer. Does the blocks mean part of the reference is not covered by SOAP alignments? What settings did you use, perhaps bowtie is set to report random hits for reads with multiple mappings while SOAP will only give you unique mappings?

          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...
