%X We present MAPSEMBLER, an iterative micro and targeted assembler which processes large datasets of reads on commodity hardware. MAPSEMBLER checks for the presence of given regions of interest that can be constructed from reads and builds a short assembly around it, either as a plain sequence or as a graph, showing contextual structure. We introduce new algorithms to retrieve approximate occurrences of a sequence from reads and construct an extension graph. Among other results presented in this paper, MAPSEMBLER enabled to retrieve previously described human breast cancer candidate fusion genes, and to detect new ones not previously known.MAPSEMBLER is the first software that enables de novo discovery around a region of interest of repeats, SNPs, exon skipping, gene fusion, as well as other structural events, directly from raw sequencing reads. As indexing is localized, the memory footprint of MAPSEMBLER is negligible. MAPSEMBLER is released under the CeCILL license and can be freely downloaded from http://alcovna.genouest.org/mapsembler/ webcite.
