  • 454 reads correct with illumina

    by 454 and illumina reads assemble 300m genome :

    my schedule is
    1 correct the 454 reads by illumina 90bp reads by Coral (the attachment)
    2 assemble by celera or newbler

    do you anyone have done it ? is there another way to do it ?

    We tried one called Nesoni to correct bacterial 454 contigs using Illumina short read data. It worked ok and corrected about 50 errors in a 6MB genome (if I remember rightly).

    We haven't continued with this approach extensively, your 300 MB sounds like a lot more of a challenge.

      yeah,thanks a lot ,i have done the work by Coral ,and assemble with the software Newbler,it has a great improve for genome size .
      for my genome is highly heterozygosis, i think it is useful !

        Can I ask, biocomfun, how you used CORAL to correct 454 reads using Illumina reads? As far as I can tell, CORAL simply takes a set of reads and does multiple alignment ... i.e. you can't specify a set of reads to be corrected and a different set of reads to be trusted and used for correction. What did you do, merge your 454 and Illumina reads into one fastq file?

          I use 30x solexa reads to correct 10x 454 reads specifically,with a improved version of Coral by author,it can specify a set of reads to correct with a different sets of data .

            I'm interested in what you mean by this, how does this work? I plan on using Coral for my current de novo project. Is it possible to obtain this per-released version of Coral?

                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...
