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>

Hi Alex,
Yes, it is possible to have different numbers of tool outputs using the <filter> tag for outputs. E.g. in the cuffcompare wrapper this code is used:
-- <data format="tabular" name="input2_tmap" label="${tool.name} on ${on_string}: data ${second_gtf.input2.hid} tmap file"> <filter>second_gtf['use_second_gtf'] == "Yes"</filter> </data> --
In practice, you should be able to use any boolean condition in <filter>.
This doesn't seem to be documented on the tool config wiki page right now ( http://bitbucket.org/galaxy/galaxy-central/wiki/ToolConfigSyntax ), but we'll add it soon.
Best, J
