Summary: Mapsembler is a targeted assembly software. It takes as input a set of NGS raw reads and a set of input sequences (starters). It first determines if each starter is read-coherent, e.g. whether reads confirm the presence of each starter in the original sequence. Then for each read-coherent starter, Mapsembler outputs its sequence neighborhood as a linear sequence or as a graph, depending on the user choice.

"Error: no local variable "counter" was set." is not a number.

Description

Mapsembler page Description and possible usages:

Mapsembler is a targeted micro-assembly software. It takes as input a set of NGS raw reads and a set of input sequences (starters). It first determines if each starter is read-coherent, e.g. whether reads confirm the presence of each starter in the original sequence. Then for each read-coherent starter, Mapsembler outputs its sequence neighborhood as a linear sequence or as a graph, depending on the user choice. Mapsembler may be used for (not limited to):

· Validate an assembly (the starter) based on de-Bruijn graph where read-coherence was not enforced. · Checks if a gene (the starter) as an homolog in a set of reads · Checks if a known enzyme is present in a metagenomic NGS read set. · Enrich unmappable reads before to try to map them with their neighbors · Checks what appends at the extremities of a contig · Remove contaminants or symbiont reads from a read set
