When I install a tool from the toolshed that has type="set_environment" as a requirement, I get this in the main.log: Creating a new record for version None of tool dependency SCRIPT_PATH for revision 5fed38c7e063 of repository mirdeep2. The status is being set to Never installed. Consequently, nothing in the tool_dependency directory is created. The tool is shown to have missing dependencies in the 'Manage installed tool shed repositories' panel. Is there something special that must be done to allow a tool to have only an environment setting as a dependency? Is there something that can be done to fix the problem, other than going into the database and changing the tool_dependency.status from 'Never installed' to 'Installed' and manually creating the subdirectories? -------------------- David Hoover, PhD Helix Systems Staff
