Overview

The Syntenic Path Assembly is an option in SynMap to do a reference genome assembly of contigs using synteny to determine the order and orientation of the contigs. To use this option, select "Order contigs by best syntenic path" under the Display Options tab. When an assembly is generated, you may download the assembled sequence (contigs are joined using 100Ns).

This algorithm also works quite well in aligning a WGS assembly between distally related organisms. See below for examples.

Selecting the Syntenic Path Assembly option in SynMap
running a syntenic path assembly in SynMap, there is an option to download the assembled sequence (contigs are joined using 100Ns).
