Dave,

I was surprised to read your report. I recently aligned 12 Streptococcus pyogenes genomes (~1.8 Mb each) using the previous release of Mauve on a G3 Mac. It took the program a few hours, but it worked fine. I know that P. syringe has a larger genome than group A streptococci, but I would have guessed that it would have aligned them. Maybe there is also a memory issue? If not, what is the theoretical genome size breakpoint for a 32 bit processor?

Aaron,

I am interested in being able to perform a simultaneous alignment of all of the fully sequenced Pseudomonas spp. Attempts with previous versions of Mauve have been unsuccessful, apparently due to the 32 bit addressing limit. However, I have access to a Mac G5-based cluster with 8 Gbytes/ node. How
difficult would it be to produce a 64 bit version of Mauve for the G5?

By the way, the recently released progressive version works great and
appears to be significantly faster when aligning the three fully sequenced pathovars of P. syringae. The new search features are extremely helpful.
