WebMar 3, 2014 · Background Genome assembly is typically a two-stage process: contig assembly followed by the use of paired sequencing reads to join contigs into scaffolds. Scaffolds are usually the focus of reported … 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 ...
