    blastn help for primer alignment to custom db

    Hello!

    I am trying to find primer pairs that will amplify across 6 individuals of the same taxa. I have forward and reverse primers(<30bp each) for each individual that were generated by QDD, and am now trying to blast the primers from each individual to the microsatellite sequences(msat + flanking regions) from the other 5 (ex. primers from A blasted to msat sequences from B,C,D,E,F). The goal is to find which primers will align in all 6 individuals so that we can order the primers and test if they amplify in the lab.

    This is the blast command I'm using right now. I want the results to be only alignments that span 100% of the query sequence. Really, a global query:local database alignment.

    >>blastn -task blastn-short -qcov_hsp_perc 100 -perc_identity 100 -ungapped -num_threads 8 -outfmt 6 -query "query.fa" -db "subject.db" -out out.out

    Unfortunately, I'm really new to this and am not very knowledgable on the subject, but does it look like this command will give me the results I am looking for? Thanks for the help!

    Multiomic Liquid Biopsy: What DNA/RNA Panels Reveal That DNA Alone Can’t
    by SEQadmin2



    Tumors contain complex mixtures of cell populations that evolve in response to treatment and host-specific factors. Tissue biopsies provide only static snapshots of a tumor’s state. But what if we could follow that evolution over time using a minimally invasive technique?

    Liquid biopsies can detect tumor-derived material circulating in the bloodstream, providing a way to study treatment response, detect emerging resistance, and discover new biomarkers. Circulating

    New Genomics Technologies Take Aim at Long-Standing Limits
    by SEQadmin2


    Researchers using sequencing and genomics tools often have to make trade-offs. They can choose between speed or scale, short reads or long-range information, or targeted panels or a view of the whole transcriptome. New technologies that have been released this year are built to address those tough choices.

    We asked six companies the same four questions to learn about their latest products. The new technologies bring a lot to the table, including rethinking sequencing
