[galaxy-user] Gain sequences after mapping reads to a reference genome

Hi all, I would like to know if mapping reads to a reference genome, through galaxy, can generate the query genome sequence? I had mapped my reads from Illumina sequencer to a reference genome through both BWA and Bowtie on Galaxy public server platform(https://main.g2.bx.psu.edu/root ). As a result, i gained the SAM files. But, i can't find how to generate the resulted assemblied genome sequence. Is there anyone know this? Any reply will be very appreciated. Best regards.
