  • Q. Cufflinks

    1. Tophat produced accepted_hits.bam
    2. samtools index produced accepted_hits.bam.bai
    3. samtools view produced accepted_hits.sam
    4. cufflinks -g reference.gff -o output_file accepted_hits.sam

    Right after typing cufflinks command,
    the messages appeared like the following:
    [bam_header_read] EOF marker is absent.
    [bam_header_read] invalid BAM binary header (this is not a BAM file).
    File accepted_hits.sam doesn't appear to be a valid BAM file, trying SAM...

    Are these messages okay and will there be no problem in output?
    Thanks in advance.

    Non-Coding RNA Research and Technologies
    by seqadmin




    Non-coding RNAs (ncRNAs) do not code for proteins but play important roles in numerous cellular processes including gene silencing, developmental pathways, and more. There are numerous types including microRNA (miRNA), long ncRNA (lncRNA), circular RNA (circRNA), and more. In this article, we discuss innovative ncRNA research and explore recent technological advancements that improve the study of ncRNAs.

    Recent Developments in Metagenomics
    by seqadmin





    Metagenomics has improved the way researchers study microorganisms across diverse environments. Historically, studying microorganisms relied on culturing them in the lab, a method that limits the investigation of many species since most are unculturable1. Metagenomics overcomes these issues by allowing the study of microorganisms regardless of their ability to be cultured or the environments they inhabit. Over time, the field has evolved, especially with the advent...
