    Tophat/Cufflinks - Transcripts biotype - protein_coding or ncRNA

    Hi

    I tried to look online on various forums for this problem, unfortunately could not seek much help.

    1. From my cufflinks output, for the various genes, I was trying to find their corresponding gene biotype and I was successful in doing it. I used the genes.fpkm_tracking file and the gtf file from ensembl, and I found out the whether my genes are protein coding or non coding genes. But can anyone tell me how to go about doing this at the transcript level. How do I find if my transcripts are protein_coding or ncRNA and if ncRNA, whether they are antisense, pseudogene, miRNA,etc.

    2. Is there an annotation file which would give me information on the transcript biotype - can someone suggest me please.

    Because when I use this annotation - Mus_musculus.GRCm38.71.gtf : This file only gives me the gene_biotype and not the transcript_biotype.
    GL456350.1 protein_coding exon 993 1059 . - . gene_id "ENSMUSG00000094121"; transcript_id "ENSM UST00000177695"; exon_number "1"; gene_name "Ccl21c"; gene_biotype "protein_coding"; transcript_name "Ccl21c-201"; exon_id "ENSMUS E00000980949";


    Any help in this regard will be highly appreciated. Thanks in advance.

    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
