[galaxy-dev] how to get raw input from GUI

Hi,

I am working on a wrapper for gatk and including

<repeat name="filters" title="filter names and expressions" help="--filterName, --filterExpression"> <param name="filter_name" type="text" value="" title="Filter name to be included in the analysis" /> <param name="filter_exp" type="data" value="" title="Filter expression to be included in the analysis" /> </repeat>

in it, however, when I reference it using

${filter.filter_exp}

it would translate 'FS > 30.0' into XXXFS __gt__ 30.0XXX

is there a way that I could keep the original text string 'FS > 30.0'? I did a quick lookup online but didn't see anything in cheetah's user guide or other places.

Thanks, Rui
