I'm writing a wrapper for RUM (RNA-Seq Unified Mapper). For those of you who aren't familiar with RUM, it produces several output files. I'm trying to capture 12 of those files in Galaxy. Here is one of the 12 nodes: <data format="tabular" name="feature_quantifications_galaxy" label="${tool.name} on ${on_string}: Feature Quantifications" /> All 12 nodes have similar syntax. When I try to run RUM from Galaxy, it's obvious that the program is executing properly. The outputs show up as pending until the execution of RUM has completed. However, the output is not being properly captured. All 12 outputs show up as being in the error state, and when I click on the bug icon I see the following in the error report: yes: standard output: Broken pipe yes: write error Those two lines are repeated literally over a hundred times. In the additional output pane beneath the error pane, It shows the output from RUM, which indicates that the tool indeed ran properly. The text is exactly what I would expect to see if I ran the tool from the command line without any problems. So basically, I'm doing something wrong in capturing the output. I have watched the screencast and perused other wrappers, but I'm not sure at this point where I'm going wrong.
