If possible, if you are assembling a lot of genome data, you really should set yourself up properly with a multiple-CPU unix box with a lot of RAM and dedicate it to assembly. Install MIRA, Newbler, Velvet, AMOS, samtools, bamtools, bedtools, Staden, phred/phrap/consed on it, and you can assemble and interconvert data to your heart's content.
> Galaxy is a wonderful and useful service but assembling genomes does require dedicated power and expertise, and preferably in house. I just forked out for a 64 CPU processor with 1 TB RAM bc we assemble lots of genomes. You don't have to go that far but a 3-4 quad processor box with 128 GB RAM and 1 TB disk should be on your mind.
