Hi everyone,

I'm trying with all my best to add an NGS tool into my local Galaxy instance.
I've added my tool in tool_conf.xml, and made a XML file with all the <command>, <param> etc... I think it's pretty ok, and everything is correctly displayed on the Galaxy interface.

However, when I execute my tool, Galaxy says to me :

Error executing tool: cannot find 'database'


And in my shell, I can see :

127.0.0.1 - - [30/May/2012:10:47:01 +0200] "GET /tool_runner?tool_id=myTool HTTP/1.1" 200 - "http://localhost:8080/root/tool_menu" "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:12.0) Gecko/20100101 Firefox/12.0"

I'm a beginner in computer sciences, so I can't understand since over 1 week what's happening ...  Any idea what's wrong with this ?
(I'm using Ubuntu LTS 12.04)

All help will be very very appreciated !

Thank you,

Marine
