  • How to determine 454 paired end adaptor sequence

    I have a list of 454 sequence data read, for running the preprocessing step, I need to find out the adaptor sequence read first.
    Do anybody know how to find out the adaptor sequence for the 454 paired-end sequence?
    Is it 454 company using a standard adaptor sequence for all of their sequencing process technique?

    Passing on some information from a contact at Sanger regarding the paired end linker sequence:

    454flx
    GTTGGAACCGAAAGGGTTTGAATTCAAACCCTTTCGGTTCCAAC
    (palindromic)

    454titanium
    TCGTATAACTTCGTATAATGTATGCTATACGAAGTTATTACG
    (and also check for its reverse complement)

    These are also given in the sffToCA documentation for the WGS assembler:
    Download Whole-Genome Shotgun Assembler for free. Celera Assembler (CA) is a whole-genome shotgun (WGS) assembler for the reconstruction of genomic DNA sequence from WGS sequencing data.

      Thanks a lot for your explanation.
      Do you have the list of paired-end adaptor sequence that using by 454 sequencing technique?
      Can provide the suitable link or website for me to find out the paired-end adaptor sequence that using by 454 sequencing technique?
      Thanks a lot for your help

        The MIRA documentation gives a few adaptors, but warns that local sequencing centers may use their own specific ones:

          Hi, thanks a lot again
          Do you have any idea about the adaptor sequence using by 454 technique to sequence bacillus genome?

            Are you talking about getting your own data for bacillus by paying a local sequencing service? If so, your sequencing center should be able to tell you the adaptor/linker sequences they use - but it will probably be the default Roche 454 sequences.

              For 454 FLX sequencing data,

              The sequence below is it the general 454 flx adaptor sequence?
              454flx
              GTTGGAACCGAAAGGGTTTGAATTCAAACCCTTTCGGTTCCAAC
              (palindromic)

              When I using it because of palindromic, should I used this:

              >454flx1
              GTTGGAACCGAAAGGGTTTGAATTCAAACCCTTTCGGTTCCAAC

              >454flx2
              CAACCTTGGCTTTCCCAAACTTAAGTTTGGGAAAGCCAAGGTTG

              I just checked, my data is 454 flx sequencing data, just I not sure about its adaptor sequence used for 454 flx.
              Thanks for your help

                No - that is the linker sequence used for paired end reads.

                    No, I'm not a forum admin - just another user.

                    I'm sorry if I added to the confusion by talking about the paired end linker sequences when you were more interested in the adapter sequences. Hopefully things are clearer now

                      haha..
                      thanks a lot for your help
                      Actually I confusing myself d...
                      I refer to the paired-end linker instead of paired-end adaptor sequence
                      I misunderstanding myself d
                      Besides that, do you familiar with some open source software, like SSAHA2?!

                        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...
