How do you map nanopore fast5 files? Is there a best practices for mapping Oxford Nanopore files to a reference?

Is there a tool that can take a tarball of fast5 files and map them directly or do they need to be converted to fastq first?
Fast5 files need to be converted to fastq first prior to mapping. There are currently no tools available to map the entire raw signal directly to a reference, although a few tools are available for identifying short sequences within the raw signal.
