Hi Nik I don't think there is a solution out of the box for all of this, but I will try to give you some pointers - others might have different or even better suggestions (my suggestion are very 'hacky'). Let me answer your questions in reverse order: - Instead of using "Add another file", display all your files as checkboxes: type="select" display="checkboxes" multiple="true" you then get a comma separated string with containing all the selected files one option to populate the checkboxes is using "dynamic_options" or "from_file" which both allow you to read the list of files stored in a extra table - A list with thousands of files to choose from is obviously not very handy. You can build a tree where you can open and collapse individual branches using type="drill_down" together with "from_file" Or as an alternative to searching, you can use "conditional" and then only display part of the list. - you can write a little tool, which allows people to select a history item (or uploads a new file) which is then stored at a new location (outside the galaxy database directory). In a second step, this tool adds the item to the table which is read by "dynamic_options" or "from_file". Using "from_file" would require a restart, but a tool reload. I hope you get a few ideas out of this Regards, Hans-Rudolf On 04/09/2014 04:34 AM, Nikhil Joshi wrote:

Hi all,

We have a local install of Galaxy that we use for testing for our bioinformatics courses. I am creating some new tool interfaces for the install. I want to create a tool that will allow a user to automatically add a fasta database to the "built-in" databases (without needing to reboot the server). Is this possible?

Along with that issue is that the number of databases for this tool can number in the thousands. Is there a way to easily search the built-in databases for the database you are looking for, and then use that database in a tool? Right now, it is an enormous drop down list which is really annoying and unwieldy.

Finally, these tools can take multiple input files, but I really don't like the way galaxy handles that where you have to continually click on "Add another file". Is there a method or work-around in galaxy where you can have a multi-file select?

- Nik.
