Hi Jake,
What is happening here is that in the command line substitution, the $filter_fxn variable is actually a wrapper object and not strictly a string. If you want to compare $filter_fxn1 to a string, you can try something like
#if str( $filter_fxn1 ) != "":
or
#if $filter_fxn1.value != "":
Thanks for using Galaxy,
Dan

I have a script that allows arbitrary filtering on a resource within a more complicated step. in the command section, I have: #if $filter_fxn1 != "" --filter_fxn1="$filter_fxn1" #end if
and
<param name='filter_fxn1' type='text' label='Filter expression for resource1' /> in the inputs section. The trouble is that when there is no text in the input text box, I'm still getting --filter_fxn1="" in my parameter string.

PS-- for simple questions like this on developing tools, should I be deferring to the galaxy-users list?
Thanks!
