    Thank you

    Thank you very much indeed Ancestro. Just the info I was after.

    But I had read this document and missed the section !!! I really was at a dead end. Apologies for taking up your time and I am grateful.

    Thanks TurnerSD, appreciated. I had put in effort and try not to waste peoples time.

    I'd already seen this one - will reread it including the references in case I missed something.

    I still do not understand the knowledge embedded within the Velvet output file called LastGraph.

    Thanks

  • Where is documentation for Velvet software assembly please.

    Greetings,

    I ask very newbi questions.

    I am trying to understand how to use Velvet (parameters and understand the output) and seek documentation, have read the manual (maybe 21 pages) but thats all I can find.

    Currently, as a test, I try to assemble about 500bp from a very well defined fastq file and do not understand the velvet output. The relevant file (I understand) is called 'LastGraph' containing about 12 contigs and 18 lines starting with the word 'ARC'. I expected a single contig. I would guess a graph could be constructed with these 12 contigs as Vertices and the 18 ARCs as edges but I cannot see this. Also the contigs are pairs which I imagine are somehow (reverse) complemented - but I also do not see this.

    Any comments welcome (especially about LastGraph format/'meaning') and pointers to documentation. I have spent maybe 2 days on this and put in effort and seem to be at a dead end.

    Thanks

    Exploring the Dynamics of the Tumor Microenvironment
    by seqadmin




    The complexity of cancer is clearly demonstrated in the diverse ecosystem of the tumor microenvironment (TME). The TME is made up of numerous cell types and its development begins with the changes that happen during oncogenesis. “Genomic mutations, copy number changes, epigenetic alterations, and alternative gene expression occur to varying degrees within the affected tumor cells,” explained Andrea O’Hara, Ph.D., Strategic Technical Specialist at Azenta. “As...

    Exploring Human Diversity Through Large-Scale Omics
    by seqadmin


    In 2003, researchers from the Human Genome Project (HGP) announced the most comprehensive genome to date1. Although the genome wasn’t fully completed until nearly 20 years later2, numerous large-scale projects, such as the International HapMap Project and 1000 Genomes Project, continued the HGP's work, capturing extensive variation and genomic diversity within humans. Recently, newer initiatives have significantly increased in scale and expanded beyond genomics, offering a more detailed...
