HI all, I just had a query about some 'missing' functionality in one of my tools, which is handled by a parameter which doesn't get shown on the preview shown in the Tool Shed - perhaps because it is inside a conditional? <conditional name="output_choice_cond"> <param name="output_choice" type="select" label="Output positive matches, negative matches, or both?"> <option value="both">Both positive matches (ID on list) and negative matches (ID not on list), as two files</option> <option value="pos">Just positive matches (ID on list), as a single file</option> <option value="neg">Just negative matches (ID not on list), as a single file</option> </param> <!-- Seems need these dummy entries here, compare this to indels/indel_sam2interval.xml --> <when value="both" /> <when value="pos" /> <when value="neg" /> </conditional> Ideally the ToolShed preview would show the dropdown combo box allowing you to pick both files, positive only, or negative only: http://toolshed.g2.bx.psu.edu/view/peterjc/seq_filter_by_id Is this a known limitation? Is there a Trello card I should follow? Thanks, Peter
