Does anyone know what would be an easy and good way to assemble a bacterial plasmid genome (5-20kb) from Illumina reads that are 150 bases long? I have at least 1000x coverage. Some time ago I tried to use soap denovo and velvet but didn't get good results so I turned to mapping reads to a reference since I had the reference. Now I don't have a reference and would need de novo assembler. The plasmids don't contain repeats.
