  • Velvet assembler ambiguous calls

    Hello,

    I'm using Velvet assembler and I've a little doubt.
    After reading Velvet documentation I know that one gap in output assembly is represented by minimum of 10 N's. And that the number of N's represent the estimated gap length.

    However I can't find information about how does Velvet treat ambiguous calls. I would like to know how Velvet represents the ambiguous calls in output contigs.fa

    Does Velvet replace ambiguous calls with a random nucleotide (A, C, T or G)?

    Thank you very much.

    I've got answer from Daniel Zerbino (creator of Velvet). In case anyone else interested:

    Velvet does not support ambiguous call, it just makes a majority call.

      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...
