Hi Donny,

Galaxy expects data to be "copied in" to its data store (by default,
galaxy-dist/database/files/), and it's not designed to access data in
the way you're suggesting.  However, there are some workarounds.
First, if the data is added to a Data Library (an admin feature,
although once a library is created, non-admin users can be given write
access to specific libraries), data can be "uploaded" to libraries
without copying it in to Galaxy.  This is documented here:

    https://wiki.galaxyproject.org/Admin/DataLibraries/UploadingLibraryFiles

The Galaxy user must have read access to the data in question to be imported.

Datasets in Galaxy can also have their path set explicitly, a feature
which some Galaxy admins have used to create a Galaxy tool that allows
users to browse their local filesystem space and "import" datasets
without copying them.

Hope this helps,
--nate
