  • A qusetion about denovo assembly 454 sequence using MIRA

    Hi,

    I use mira to do assembling on my 454 sequence, but the problem is if there are two differnet nt in the same position, the contig sequence will be change.

    for example:
    contig1: AAAARTTTYTCCCCGGGG
    member1: AAAAGTTTCTCCCCGGGG
    member2: AAAAATTTTTCCCCGGGG

    it means
    AG =R
    CT =Y
    AC=M

    How can change the R Y M to ATCG?

    Thank you.

          Thank you so much! sklages
          It work when I set the -job:sanger, but not work well when set -job:454.

          The new problems is how to set the ends clip in MIRA,
          I try -CL:emlc and -CL:emrc, some of my sequences have different in the ends, but it not work
          example is in cap3, I can set -y 15, and if the ends different lower than 15bp , it clipped.
          In MIRA, it can not assembly when set -CL:emlc=no,emrc=no

            well, it should work with -job:454 as the manual doesn't distinguish
            sequencing chemistries at this point.

              I use 2.9.37 version before, maybe some other parameter different when I set -job:454 or sanger, now I download 2.9.44 version, use -CLec=yes to clip the ends of sequence, but the clipping part is too long, I want set the clipping length lower than 15bp; if clip longer than 15bp,I think the two reads can not assembly. How to set it? Thank you.

                  Current Approaches to Protein Sequencing
                  by seqadmin


                  Proteins are often described as the workhorses of the cell, and identifying their sequences is key to understanding their role in biological processes and disease. Currently, the most common technique used to determine protein sequences is mass spectrometry. While still a valuable tool, mass spectrometry faces several limitations and requires a highly experienced scientist familiar with the equipment to operate it. Additionally, other proteomic methods, like affinity assays, are constrained...

                  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...
