    LASTZ error

    Hi,
    I'm trying to do a lift over between two versions of M. zebra, for which I need a chain file. I'm trying to do a whole genome alignment using LASTZ, and then chaining using axtChain.

    But I'm getting an error with LASTZ. Well not exactly an error: it seems to run forever and there's no output. The command I'm using is

    lastz GCF_000238955.2_M_zebra_UMD1_genomic.fna[multiple] M_zebra_v0.assembly.fasta --format=axt --strand=both --nochain --gapped --gap=400,30 --inner=2000 --hspthresh=2200 --gappedthresh=6000 --seed=12of19 --notransition --ydrop=3400 --scores=HoxD55.q

    I noticed that when I run the command with --chain, it runs. But with the --nochain option, the command runs forever and no output is produced.

    From Collection to Sequencing: Why Sample Preparation and Preservation Define Sequencing Data
    by SEQadmin2


    Data variability is still an issue in sequencing technologies despite the advances in reproducibility and accuracy of these platforms. But the problem does not originate in the sequencing itself, but in the previous steps, before the sample reaches the sequencer.


    The first step is collection, followed by preservation and sample preparation for analysis. Most scientists overlook those steps, but not being careful might just be skewing the experiment’s results.

    Environmental Genomics in the Age of NGS: From Microbes to Conservation Strategies
    by SEQadmin2

    Studying ecosystems means dealing with complex, multi-species communities that are hard to observe at scale. This complexity, however, hides many important questions to be answered, from how biogeochemical cycles work and how climate change can affect species distribution to how conservation strategies can work best.


    Genomics, particularly since the expansion of NGS, has transformed ecosystem ecology. By sequencing environmental DNA, we can now assess biodiversity without direct...
