Hi all,
 
In my tool-config I try to use conditional number of output files. Is this possible? For input files the <CONDITIONAL> and <WHEN> statements are able to do that. What about output files?
If I have four listed I will always get 4 history items in my work flow. If I only generate 3 I still get 4 items of which one contains no data. I want to prevent this cluttering by providing the user a selective set of output files.
 
Basically can I modify the below using input parameters to generate 3 or 4 files? (not using a zip container).
Any clues appreciated.
 
  <outputs>
        <data name="out_1" format="tabular" label="Coords" />
        <data name="out_2" format="tabular" label="Delta" />
        <data name="out_3" format="png" label="Plot" />
        <data name="out_4" format="text" label="Console log file" />
  </outputs>
