[galaxy-dev] environment variables and paths for toolshed tools

Are there any environment variables that are honored by toolshed installed tools? I tried creating a tool that uses ${GALAXY_DATA_INDEX_DIR} or $GALAXY_HOME, then uploaded it the test toolshed, then installed it automatically. Neither of these resolved to what I expected. I don't want to hard-code the path in the xml tool file, but rather have a default location for other executables and jar files. How should this best be done? David Hoover Helix Systems Staff
