Hey Ryan,

Yes, this is exactly why.  By default, galaxy expects that anything written to stderr means that there was a failure, though you can change this by using the error_code syntax (among other options) found here:  https://wiki.galaxyproject.org/Admin/Tools/ToolConfigSyntax

 Hi - I implemented a tool I us into Galaxy but when I run the tool view Galaxy, Galaxy thinks the tool failed.  I checked the output file the tools create, and it succeeded. 

How do I tell Galaxy that a tool it ran was successful?  Is it something in my XML file?  The tool is outputting some info to stderr.  Could this be why?
