Assembles de novo short read sequencing data. An assembler for the de novo assembly of large genomes using short sequence reads via jumping extension and read remapping. JR-Assembler extends a read by other whole reads, that is, it makes a jump. It uses a dynamic back trimming process to avoid extension termination due to sequencing errors. The tool achieves a superior performance on memory use and central processing unit time than most current assemblers when the read length is 150 bp or longer.
