The de novo assembly process has two stages:
- First, simple contig sequences are created by using all the information that are in the read sequences. This is the actual de novo part of the process. These simple contig sequences do not contain any information about which reads the contigs are built from. This part is elaborated in How it works.
- Second, all the reads are mapped using the simple contig sequence as reference. This is done in order to show e.g. coverage levels along the contigs and enabling more downstream analysis like SNP detection and creating mapping reports. Note that although a read aligns to a certain position on the contig, it does not mean that the information from this read was used for building the contig, because the mapping of the reads is a completely separate part of the algorithm.
