    cuffdiff problems

    These days I was analyzing my RNASeq data by cufflinks,then I found some problems when I run cuffdiff.The program always died with "Segmental fault" after runing some time,my command likes below,

    "cuffdiff -C pairwise_compare_list -o cuff_diff -p 30 -b genome.fa -u --labels 0.5hDex,0.5hNaCl,2hDex,2hNaCl,0 genome.gtf 0.5hDex/abundances.cxb 0.5hNaCl/abundances.cxb 2hDex/abundances.cxb 2hNaCl/abundances.cxb 0/abundances.cxb".

    But cuffdif runned successfulled when I runned with
    "cuffdiff -C pairwise_compare_list -o cuff_diff -p 30 -b genome.fa -u --labels 0,0.5hDex,0.5hNaCl,2hDex,2hNaCl genome.gtf 0/abundances.cxb 0.5hDex/abundances.cxb 0.5hNaCl/abundances.cxb 2hDex/abundances.cxb 2hNaCl/abundances.cxb",
    the only diff is I changed the labels order. I don't known why.
    Does the sample named by interger can't appear at the end of sample labels ?

    Even it runned successfulled,when I check results I found that all five comparisons in contrast file "pairwise_compare_list" were done in "genes_exp.diff", but only three comparisons in "isoforms_exp.diff". I don't known why,because everything looks well. I have met this problem befor,too.

    Anybody can help me?

    16S/ITS Profiling vs. Shotgun Metagenomics: What Changes in Your Workflow?
    by SEQadmin2





    NGS has revolutionized clinical microbiology by offering new ways to identify and surveil pathogens without prior knowledge of the target. One popular approach is 16S rRNA and ITS amplicon sequencing, which targets specific microbial markers. But studies are increasingly incorporating shotgun metagenomics, a technique that sequences all DNA from a sample without targeting specific microbial markers. This approach allows more detailed taxonomic classification,...

    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
