    RepeatModeler - problem with creating library for RepeatMasker

    Hi everyone!

    I was trying to build library with RepeatModeler from fasta seqences (containing only transposons) of some species of fish. Let's say that I've done it, but I'm not sure if it's correct. My prepared fasta file contains 1072 sequences of fish, but the library created by RepeatModeler (file consensi.fa.classified) contains ONLY 8 sequences and I wonder if it isn't too less. Below I add exact command lines to show You what I've done, cause mabye I did something wrong through the process of creating the library. In addition to this, RepeatModeler didn't create .xdf file which I've expected after reading manual. Here's the link to example run: http://www.repeatmasker.org/RepeatModeler.html

    Command lines: (Based on http://www.repeatmasker.org/RepeatModeler.html)
    1. BuildDatabase -name Database -engine ncbi Mobile-elements.fasta
    2. nohup RepeatModeler -engine ncbi -database Database >& run.out &

    From manual:
    -database
    The prefix name of a XDF formatted sequence database containing the genomic sequence to use when building repeat models. The database may be created with the WUBlast "xdformat" utility or with the RepeatModeler wrapper script "BuildXDFDatabase".

    However there is no script like "BuildXDFDatabase" and WUBlast was replaced by AB-BLAST, which you have to pay for license.

    I hope that someone can answer me, cause I doubt that this library is correct and i I can't go on with my project. Thanks in advance

    Nine Things a Sample Prep Scientist Thinks About Before Sequencing
    by SEQadmin2


    I’m not a sequencing expert. I’m a purification scientist who uses NGS to evaluate workflows my group develops. With this perspective, we think about the sample first and the NGS workflow second. The sequencer is an exceptionally honest reporter, but it can only report on what you give it, so whether you get clean, interpretable data from an NGS workflow is largely determined before you begin.

    Here are nine questions we think about, in roughly the order they matter, before...

    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.
