Hello, The guidelines regarding symbolic links in data library uploads in covered (with examples) in this wiki: http://wiki.galaxyproject.org/Admin/Data%20Libraries/Uploading%20Library%20F... The basic of library loading are in this wiki, including instructions for uploading a new version of existing files: http://wiki.galaxyproject.org/Admin/Data%20Libraries/Libraries Going forward, you will want to use the galaxy-dev@bx.psu.edu mailing list instead for questions about local installs - this will give your questions the best visibility to the development community: http://wiki.galaxyproject.org/Support#Mailing_Lists Hopefully this helps!

Hi all,

I created data libraries using options "Upload files from filesystem paths" and "Link to files without copying into Galaxy". It worked but I use symbolic links because my data are frequently updated.

The problem is that Galaxy takes the real link ("external_filename" column in "dataset" table) and doesn't find the files.

Is there a way for galaxy to take the symbolic link in the database.

Thanks in advance for your help! Cheers,
