Options and filters should work for what you need:

Hi All,
I'm trying to dynamically load labels from a BioConductor ExpressionSet file (binary .RData) into a select item type. This works just fine, but with a few caveats.
Example (for reference, this is from a modification of https://trac.nbic.nl/galaxytools/browser/trunk/tools/proteomics/NPC/AMC/DE.x...):
<code file="CL_code.py"/> ... <page> <param name="eset" type="data" label="Expression set" format="rdata" force_select="True" help="An R data file containing an ExpressionSet"/> </page> <page> <param name="label" type="select" dynamic_options="get_label(eset,False,'class')" force_select="True" label="Variable to test" size="20" help="Name of the variable subject to testing" /> ...
I would like to remove the deprecated page tags here (also then the tool can be added to a workflow). However if I do that and then select an ExpressionSet file, the select list does not update. It only works when loading the page for the first time, or when I use the page tags. For text files the solution would be easy; just use type="data_column" and data_ref="yourinputfileparamname" and it auto-updates the select field (though not with the actual column names but that is another issue). With a binary file this is not possible, therefore the dynamic_options feature is needed to do this.
Does anyone know of a way to get this to work without using the page tags?
Kind regards,
