  • Filter SOLiD reads for gene of interest then assemble

    Hi,

    There are several SOLiD runs in the Short Read Archive from different haplotypes of the species that I work on.

    I want to download this data, extract all of the reads that are homologous to my gene of interest, then analyse and possibly assemble them.

    What programs would you use to

    -filter the SOLiD reads and extract reads homologus to my gene

    -clean any primers/repeats from the sequences

    -assemble or analyse the reads.


    I have some experience with Linux, Perl and analyzing 454 data. But I am mainly a wet lab biologist.

    Thank you in advance.

    Hi John,

    I would start this way - of course there may be better options

    -obtain the sequence of your gene and surrounding regions

    -convert to colour space

    -align reads against this sequence (bwa, bioscope, bfast etc)

    -use perl/grep to get sequences of those reads which aligned.

    -filter - with Galaxy, R, or FastX etc

    -realign to check for any differences due to filtering (if any)

    Good luck
    Colin

      Thankyou, that was exactly the reply I was looking for.

      All of the programs seem to be installed on my department's bioinformatics server. Now I just have to work out how to use them.

      Thankyou

        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...
