    Calculating heterozygote bam2count without gff reference

    Hey everyone,

    I have Illumina mRNA Seq data from crosses of two DH brassica napus lines (called lines 3 and 4 => 4 sets: 3x3, 4x4, 3x4, 4x3)
    I created a de novo assembly of the 3x3 with Illumina (-> fasta file),
    mapped the other 3 crosses vs this reference with bowtie2 (-> sam files),
    did SNP calling with samtools and vcftools (-> vcf files).


    Now I want to analyze the 3x4_vs_3x3 (and 4x3_vs_3x3) mapping to find out if certain code fragments are inherited only maternally/paternally.


    So I know there is a routine out there called heterozygote bam2counts here, but this is designed to work with reference (gff) files.
    So my question is: How can I alter the code to work with my de novo assembly? I understand, that it may work somehow with the use of bedtools and the intersect function.

    I'm still new to seqencing and the adjacent bioinformatics. So if anyone can point me in the right direction, that would be very helpful!

    Thank you for reading,
    Simon

    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
