  • Question about preventing N's from Oases assembly

    Hi,

    I haven't heard back from the authors so hope someone can help me here.

    I ran a velvet/oases assembly with no scaffolding in mind.
    I am using velvet 1.2.08, and oases 0.2.08

    1. For velvetg, '-scaffold no' was set
    2. For oases, '-scaffold no' is already the default (according to the help screen), so I left as is.

    here were my commands after velveth:

    $ velvetg nlab_25 -read_trkg yes -scaffolding no
    $ oases nlab_25 -ins_length 145

    Yet, the transcripts.fa in the kmer25 assembly contains 'Ns' , which I am assuming are the 'gaps' from the scaffolding option.

    How can I make oases not scaffold?

    (I also ran oases with '-scaffolding no' option, but the transcripts.fa still produced N's in the contigs)

    Strategies for Sequencing Challenging Samples
    by seqadmin


    Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...
