  • 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..

                      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?!

                        During the COVID-19 pandemic, scientists observed that while some individuals experienced severe illness when infected with SARS-CoV-2, others were barely affected. These disparities left researchers and clinicians wondering what causes the wide variations in response to viral infections and what role genetics plays.
