For example, at 400 kbp, the orientation errors with the graph were comparable to the orientation errors of the graph-less approach at 900 kbp. things to do in tulum at night https://beyondwordswellness.com

Contigs or Scaffolds for De novo genome assembly?

WebUnlike some assemblers where scaffolding is performed after contig formation, Geneious scaffolding is integrated into the contig assembly process. When there is strong support for scaffolding, it may take precedence over potentially conflicting standard contig formation. For this reason, Geneious can't be configured to produce both scaffolds ...
