Hi Thanks for your answer, and for pointing me to the right mailing list. My tool actually feeds data libraries. It works in a similar way as the "Copy data into Galaxy? No" functionality, in the sense that it creates symbolic links rather than duplicating files, but it also provides an interface to browse and select files in a finer way. So my tool is already functional and my only problem is that the tomcat user cannot create symlinks in folders created by Galaxy, because it doesn't give write permissions to the group. I could do something like a chmod 775 in a daemon, but I would rather avoid that. Can anyone help me further? G. Le 10/04/2012 04:39, Jennifer Jackson a écrit :

Hello,

I am going to forward your question over to the galaxy-dev@bx.psu.edu mailing list so that it can get more visibility in the development community. That list is probably where you will want to post regarding similar topics in the future: http://wiki.g2.bx.psu.edu/Support#Mailing_Lists

To get things started, I am wondering if you are asking about datasets in histories or data in libraries? Parts of your question seem to refer to both, or I have misunderstood (my apologies!).

If about data in libraries, then you can get around this by not actually moving the data into the Galaxy directory structure at all, and instead just link in data from some other location on the filesystem (where you can control the permissions). See the "Copy data into Galaxy? No" option described on this wiki: http://wiki.g2.bx.psu.edu/Admin/Data%20Libraries/Uploading%20Library%20Files

Other data/lib/security related links, mostly admin UI: http://wiki.g2.bx.psu.edu/Learn/Security Features http://wiki.g2.bx.psu.edu/Admin/Data Libraries/Libraries http://wiki.g2.bx.psu.edu/Admin/Data Libraries/Library Security

Hopefully this helps or some more discussion on the galaxy-dev list about your question will find a solution,

Hi,

I would like folders created by Galaxy under the location defined by the "file_path" parameter (which defaults to database/files) to be created with permissions 775 instead of 755. Is this possible?

The reason for me asking this question is that I have developed an external tool (running under Tomcat) for feeding Galaxy libraries. And my tomcat user needs to be allowed to write to the mentioned folders.

Any ideas?
