Assembles reads obtained with new sequencing technologies (Illumina, 454, SOLiD) using MPI 2.2. Ray allows to reduce the number of contigs and the number of errors. It can serve as a basis to develop an assembler that can be of universal utilization. The tool can calculate assemblies in parallel using message passing interface. Ray performs very well on mixed datasets and helps to assemble genomes using high-throughput sequencing.

A light and efficient assembler that perform well for small genomes (not tried on eucaryote ones), with good computer memory gestion (the only one that didn't crash because of a segmentation fault!).
