Hi all,<br><br>So I am writing XML files for an analysis pipeline.  The first step in the pipeline is to index the reference, the resulting files of which I have put into the files_path directory that I get from using $output.files_path.  But then I want to be able to get access to that path in a subsequent step when I choose the output of the indexing step as the input to the next step.  So I have the user choose the indexed output (which is just an html page with links to the indexed reference files), and then I try to use $input.files_path.... and that doesn&#39;t work.  Am I thinking about this in the right way?  How would I find the files_path that was created for the output of the previous step so that I can use it as an input directory for the current step?<br>
