Hi, Ata Roudgar

It is indeed a bug. Thank you very much for the excellent and *helpful* report!

We now have a fix for this on the release_15.05 branch of the github repository:

It should fix the issue but please let us know if it doesn't. Sorry for the trouble.

I am a computer cluster admin and I am trying to install galaxy on our cluster. I used galaxy-release_15.05 and because we need to serve Galaxy at a sub directory, e.g. irida-galaxy I modified the options prefix and cookie_path in the galaxy configuration file as follow:

prefix = /irida-galaxy
filter-with = proxy-prefix
cookie_path = /irida-galaxy

We use apache as an interface with the Following configuration:

<Proxy http://localhost:9010>
    Order deny,allow
    Allow from all

RewriteRule ^/irida-galaxy$ /irida-galaxy/ [R]

Everything works fairly good. Now I want to create a Dataset Pairs. first I uploads some fastaq files, e.g.,


then I choose: "Build List of Dataset Pairs" (See Fig-1 attached)

There is a window appears on my screen with the title: Create a collection of paired datasets. Now I am able to choose a name and save the paired collection. However, once I click on "Create list" buttons I receive a error message on top of the windows:

"An error occurred While creating this collection: Not found

See Fig-2 attached. To be able to search the cause of error I turn on the "Browser Consul" on my web browser and notice that the error is related to the following web form post:


Which makes sense because such address do not exist. The address should be


So the prefix (irida-galaxy) is missing before /api/histories...../dataset_collection

Is it a bug or am I missing something?

Please note that such error does not appear when I do not use prefix in my galaxy configration.
