Hi! One more question according change set 2812: Add a new option, 'allow_library_path_paste' that adds a new upload page ("Upload files from file system paths") to the admin-side library upload pages. I am not sure where to add this option- i added to universe_wsgi.ini: allow_library_path_paste = True allow_library_path_paste = /somepath/ both didnt work- how can i enable the "allow_library_path_paste" option? thanks! mat Greg Von Kuster schrieb:
Change set 2812 will be included in a release to the distribution today - here are details of a new option that we're hoping will provide what is needed for most labs.
Add a new option, 'allow_library_path_paste' that adds a new upload page ("Upload files from file system paths") to the admin-side library upload pages. This form contains a textarea that allows Galaxy admins to paste any number of file system paths (files or directories) from which Galaxy will import library datasets, saving the directory structure (if desired). Since such ability allows admins access to any file on the Galaxy server which is readable by Galaxy's system user, this option is disabled by default, and system administrators should take care in assigning Galaxy administrators when this feature is enabled. Controls on what files are accessible to this tool based on ownership or other properties can be added at a later date if there is sufficient interest for such features.
This commit also includes a checkbox on the "Upload directory of files" page (as well as the new "Upload files from file system paths" page above) that will prevent Galaxy from copying data to its files directory (by default, 'database/files/'). This is useful for large library datasets that live in their own managed locations on the file system, this will prevent the existence of duplicate copies of datasets (but means administrators must take care to manage data - moving or removing the data from its Galaxy-external location will render these datasets invalid within Galaxy).
One unique feature to be aware of: when using the "Copy data into Galaxy?" checkbox on the "Upload directory of files" page, any symbolic links encountered in the chosen import directory will be made absolute and dereferenced ONCE. This allows administrators to link large datasets to the import directory, rather than having to make full copies, while being able to delete such links after importing. Only the first symlink (the one in the import directory itself) is dereferenced; all others remain. See the following for an example:
library_import_dir = /galaxy/import
% ls -lR /galaxy/import /galaxy/import: total 6 drwxr-xr-x 2 nate nate 512 Oct 1 11:31 link/
/galaxy/import/link: total 10 lrwxrwxrwx 1 nate nate 71 Oct 1 10:38 1.bed -> ../../../home/nate/galaxy/test-data/1.bed lrwxrwxrwx 1 nate nate 60 Oct 1 10:38 2.bed -> /home/nate/galaxy/test-data/2.bed lrwxrwxrwx 1 nate nate 11 Oct 1 10:38 3.bed -> ../../3.bed lrwxrwxrwx 1 nate nate 35 Oct 1 11:30 4.bed -> ../../galaxy_symlink/test-data/4.bed lrwxrwxrwx 1 nate nate 41 Oct 1 11:31 5.bed -> /galaxy/galaxy_symlink/test-data/5.bed
% ls -l /galaxy/3.bed lrwxrwxrwx 1 nate nate 60 Oct 1 10:39 /galaxy/3.bed -> /home/nate/galaxy/test-data/3.bed
% ls -l /galaxy/galaxy_symlink lrwxrwxrwx 1 nate nate 44 Oct 1 11:30 /galaxy/galaxy_symlink -> /home/nate/galaxy/
In this example,
1.bed is a relative symbolic link to the real 1.bed.
2.bed is an absolute symlink to the real 2.bed.
3.bed is a relative symlink to ../../3.bed, aka /galaxy/3.bed, which itself is a symlink to the real 3.bed.
4.bed is a relative symlink which follows another symlink (/galaxy/galaxy_symlink) to the real 4.bed.
5.bed is an absolute symlink in the same fashion as 4.bed
If the 'link' server directory is chosen on the "Upload directory of files" page, and "Copy data into Galaxy?" is checked "No", the following files will be referenced by Galaxy:
/home/nate/galaxy/test-data/1.bed /home/nate/galaxy/test-data/2.bed /galaxy/3.bed /galaxy/galaxy_symlink/test-data/4.bed /galaxy/galaxy_symlink/test-data/5.bed
The Galaxy administrator may now safely delete /galaxy/import/link, but should take care not to remove the referenced symbolic links (/galaxy/3.bed, /galaxy/galaxy_symlink).
Not all symbolic links are dereferenced because it is assumed that if an administrator links to a path in the import directory which itself is (or contains) links, that is the preferred path for accessing the data.

Dear all,
to echo what Abhi said: we are also currently looking of ways to automatically import data sets (libraries) into Galaxy without having to manually trigger the import via the administration interface, and ideally while keeping the data in the original place. The idea here is to have multiple tools all point at the original 'source data' without having to replicate terabytes of data.
Not quite sure how feasible this is in practice, but it certainly would be incredibly helpful.
Best,
Oliver

HI Greg
Thanks for a quick reply and making some requested changes. However I am not still sure if importing NGS data will help in long run.
For Centers generating NGS data which could 2-3 T.B / week depending on no. of sequencers I think importing another copy of raw data into galaxy workspace will be asking for lot of disk space. I understand it is a neat way of doing things as it becomes agnostic of the raw data location but might not be the best way for handling huge data in long run for centers like ours.
Please correct me if I am wrong. I think we could also have a simple option without having to import the data and just using it for analysis from the current location, also storing results at the same location. That way in future even if the data set is moved analysis also stays with it.
Let me know what you feel. I will be happy to know if there are any other smart reasons of importing the data in galaxy workspace just for curiosity sake.
Thanks, -Abhi

The Galaxy distribution includes the enhancements to which I previously referred for uploading history files. Uploading files to a history now creates a Galaxy job just like any other tool, and can be run on a cluster node, allowing upload of very large files. The initial pass of this work is also completed for uploading to a Data Library, but this enhancement is still in test, so it should soon be available in the distribution.
Do you want to avoid having to import at all (e.g. allow Galaxy to refer to datasets that live in their original locations)? This is not currently possible, but if this is what you are looking for, we can consider some additional options on the current upload form, or possibly a new, separate form.

Just wondering if there has been any progress made on this end. I am sorry I was not able to follow it up on Assaf's suggestion due to other things at work.
I did try the latest version of galaxy and looks like the files are still transferred over HTTP before they could be used in the galaxy workspace. Also I would again like to highlight that many labs might want to use the local instance of galaxy and prefer to point to a local path where the file is being stored. That way we will have both the benefits of using a cool GUI and process data stored locally.
Let me know if you guys need some feedback or have more questions. I will be happy to discuss them.

Hello Abishek,
We are currently in the process of significantly enhancing the current Galaxy upload utilities, and the new version should eliminate the issue you've raised about the time needed to upload large files via HTTP ( not for making an initial copy of the file in the Galaxy environment ). However, it will probably not be ready for release for a few more weeks, so if you can take advantage of Assaf's script in the meantime, that's great. ¨ÜI can't guarantee that all Galaxy features will function correctly if you do this though.
Assaf, have you found that using your script breaks anything?
Also, if you upload a file to a library rather than a history, multiple users can "import" the library dataset into their history for analysis, but there is only 1 file on disk ( users are pointing to it from their histories ). ¨ÜBut uploading a file to a history will create a new copy of the file each time it is uploaded.

Hi All
I recently came to know about NGS analysis on galaxy during ISMB. Getting excited I tried couple of things basically to play with it.
Few comments : I may have interepretted something described below in a wrong way. My apologies before hand.
On a standalone installation of galaxy while I was trying to explore one FASTQ(sequence) file. It takes considerable (> 20 min) for a fastq file to get uploaded (2 GB).
Are you using the Galaxy upload utility to create an item in your history that points to the dataset file on disk?
Yes that is precisely correct, I am trying to upload a solexa FASTQ file but on a standalone galaxy installation from my local file system.
I am not sure what is the rationale
behind that. Ideally I think there should be no need to upload such heavy files into the workspace.
A data file that originates from a place external to Galaxy must be uploaded into Galaxy so that the disk file can be placed in the location configured in the Galaxy config file. ǃÜAlso, when data is uploaded to
Galaxy ( either to a history or a library ), several database table settings are created that are used by various Galaxy features.
They could actually be used straight
Thanks for the clarification but I am not sure this will help a lot of people who are interested to install and run galaxy locally mainly for the following reasons. May be it is just local to me.
A. We already one instance of data saved on the local file system B. Making another copy via galaxy will eat away a lot of space in long run. C. The time needed to import the files into galaxy space is huge
away by the path specified.
What do you mean by "the path specified"?
Well what I mean was a way to specify the path of the file/run on the lcoal file system and galaxy could directly pick it up from there rather than uploading it into its own space. Now I understand this might not work based on the way the system was designed.
Also is there any way to access the
scripts for analysis on the command line. I know this undermines the main aim of working with galaxy but rite now I am concerned about the performance/time.
You should be able to run any Galaxy tool from the command line as long as you have all of the tool's required binaries in your path. ǃÜHowever, running
a tool from within Galaxy should generally not be any slower than running it outside of Galaxy, depending, of course, on what you are doing.
Ok I was under the impression that running from SHELL will eliminate the step of uploading them into galaxy file space.

I will be happy to discuss more about this in case you have some comments/questions for me.
