    Segmentation fault (core dumped) in Samtools

    Hi, All,

    I want to map the RNA-seq BMA files back to the reference, and I used the samtools pileup command. It always shows the error "Segmentation fault (core dumped)".

    It should not be the problem in the reference genome, because I have tried "fold" command to format the reference genome, as well as the "faidx" in samtools. They did not work. Strangely, for different BAM files, the pileup sometimes shows the error at the very beginning, some times stopped at chr6, while some other times shows the errors at chr10 or later chromosomes.

    My command is "samtools view -u Inputfile (BAM) | samtools pileup -vcf hg19.fa - > output". However, when I tried Partek, it runs very well.

    Anyone has any idea what is the problem with these BAM files? What I should do to fix these bugs/modify the BAM files?

    Thanks a lot.

    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
