# HG changeset patch -- Bitbucket.org # Project galaxy-dist # URL http://bitbucket.org/galaxy/galaxy-dist/overview # User Dan Blankenberg dan@bx.psu.edu # Date 1283439625 14400 # Node ID fa1d4be027649ad4d745c62a053e024fe2db35e9 # Parent 04c59f0a5202a89731f76b33525a4e753e0cfa42 Add 'NullToolOutputActionOption' to tool output dataset actions. This action option is used implicitly when no ToolOutputActionOption's have been defined. This will allow e.g. setting a metadata value to a static value on a per ToolOutput basis.
Example which sets the strand assignment of an interval dataset to column 10: <outputs> <data format="interval" name="output1"> <actions> <action type="metadata" name="strandCol" default="10"/> </actions> </data> </outputs>
