Restarting Galaxy after adding a new tool
From Ucsbgalaxy
Whenever we add a tool to the tool_conf.xml file in galaxy-dist, there is a second xml file (integrated_tool_panel.xml) that changes as well. This second xml should mirror tool_conf.xml, and it is the xml that determines the workflow tool menu.
The integrated_tool_panel.xml gets re-written every time galaxy restarts. So, if you add a new tool, delete the integrated_tool_panel.xml file in galaxy-dist. When you restart galaxy, the file will be re-written and will mirror the tool_conf.xml file.
This probably sounds a bit confusing and convoluted, but I hope it makes some sense! Here is a link with more detail from the galaxy wiki:
