To unpack this mystery, you need to follow the chain from tool_conf.xml (that's what the tool menu is made from) to the actual tool directory and xml file name - eg: rerla@rosst61:~/rgalaxy$ grep -i group tool_conf.xml .. <tool file="stats/grouping.xml" /> .. That means you need to look in [galaxyroot]/tools/stats for grouping.xml to understand what the tool menu entry is going to do. The actual command is found in the first few lines of the tool xml file: rerla@rosst61:~/rgalaxy$ head tools/stats/grouping.xml <tool id="Grouping1" name="Group" version="1.9.4"> <description>data by a column and perform aggregate operation on other columns.</description> <command interpreter="python"> grouping.py $out_file1 .... so the python script you want is in /tools/stats/grouping.py - I'd be surprised if that's AWOL from a fresh mercurial clone? Now for the harder part: unfortunately the error message was missing, but my first guess is that your Python does not (yet) have rpy installed. There's a slew of dependencies described at https://bitbucket.org/galaxy/galaxy-central/wiki/ToolDependencies I hope this helps?

Hi Peter,

I can't help you with that, so I'm going to forward this to the galaxy-user mailing list, galaxy-user@lists.bx.psu.edu, where presumably someone will know the answer.

Hi, I have configured Galaxy on my desktop and it appears to be running fine. However, I suspect that I am missing tools from the galaxy-dist/tools. When I try to run the 'group' command from the join, subtract and group tab I get this error below:

And when I look in my computers directory (galaxy-dist/tools) for the py scripts there isn't a script for 'join, subtract and group'.  This is also the case for Graph/Display data. Thus, when I try to run Graph/display data I get the same error. How can I rectify this?  I configured the Galaxy suite yesterday, following the on-line Galaxy tutorial. Is it possible for somebody to forward the relevant py scripts for my to place in my galaxy-dist/tools directory.

 I look forward to hearing your advice,         Pete
