  • MetaVelvet-SL Memory Issue

    Hey guys.

    Been trying to run MetaVelvet-SL, but having trouble with memory usage. To be specific, I can't seem to get it to run even with 128 gb of memory.

    A few specifics:
    1.) I am trying to assemble around 30 million sequences.
    2.) They've gone through the first two steps fine.
    3.) I'm at the chimeric node step, and my code is just: 'meta-velvete [dir]', which is just the command and the directory where everything is stored. I leave everything else to be preset.

    This is the error I keep on getting: 'No more memory for memory chunk!'

    I guess firstly, do anyone else run into this problem with Metavelvet-SL? Secondly, anyone found a way to reduce mem usage? Even with the test sample from the MetaVelvet-SL website (HMP-small), it was already using like 16 gb of memory.

    I've tried contacting the authors directly, but no answer yet.

    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...
