    Glimmer: Multifasta analysis

    Hi everyone.
    I am new user at glimmer. We have a bacterial genome in multifasta, contigs. We can predict the ORF, if we could a complete genome in one fasta, we could, but we with Multifasta, we can make a a lot of things and I'm pretty sure that we're wrong.

    First, we separate the Genome.fas in 128 fasta files (beacuse it has 128 sequences), for make a *.train file we create a lot of *.train for any contig and put them all together in one file run.train

    Code:
    long-orfs -n -t 1.15 Contig1 run1.longorfs && extract -t Contig1 run1.longorfs > run.train
    ...
    long-orfs -n -t 1.15 Contig128 run128.longorfs && extract -t Contig128 run128.longorfs >> run.train
    then we create a *.icm model

    Code:
    build-icm -r model.icm < run.train
    but I compared it with other analysis of my friend, for he, all *logorfs are the same name, so he replace in any line this file. But my friend and my, we can the SAME NUMBER OF ORF!!!.

    Code:
    long-orfs -n -t 1.15 Contig1 [B]run1.longorfs[/B] && extract -t Contig1 [B]run1.longorfs[/B] > run.train
    ...
    long-orfs -n -t 1.15 Contig128 [B]run1.longorfs[/B] && extract -t Contig128 [B]run1.longorfs[/B] >> run.train
    Code:
    build-icm -r model.icm < run.train
    So, my friend and my, we can the SAME NUMBER OF ORF!!! although we did diferent things. I'm pretty sure that we're wrong.

    So. How do you analyse MultiFasta with Glimmer?
    And how do yu extract the fasta from *.predict file in mulifasta?

    Please, healp.

    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...
