I am not familiar with PacBio NGS plateform and not sure galaxy has deveopled long read from PacBio. You can send your question to them. If not, Lasergene from DNAStar will do. They have input data for PacBio. Talk to them. GoodLuck!
I had a look at the PacBio webpage and they give some suggestions. Here's the link: http://www.pacb.com/products-and-services/analytical-software/ and that's where one can download the software: http://www.pacb.com/support/software-downloads/ and here are some tutorials: http://www.pacb.com/products-and-services/analytical-software/devnet/
