A1 Wang, Jian A1 Yang, Huanming A1 Yu, Jun A1 Li, Songgang T1 RePS: A Sequence Assembler That Masks Exact Repeats Identified from the Shotgun Data JF Genome Research JO Genome Research YR 2002 FD May 01 VO 12 IS 5 SP 824 OP 831 DO 10.1101/gr.165102 UL http://genome.cshlp.org/content/12/5/824.abstract AB We describe a sequence assembler, RePS(repeat-masked Phrap with scaffolding), that explicitly identifies exact 20mer repeats from the shotgun data and removes them prior to the assembly. The established software Phrap is used to compute meaningful error probabilities for each base. Clone-end-pairing information is used to construct scaffolds that order and orient the contigs. We show with real data for human and rice that reasonable assemblies are possible even at coverages of only 4× to 6×, despite having up to 42.2% in exact repeats.[The following individuals kindly provided reagents, samples, or unpublished information as indicated in the paper: P.
