I am trying to integrate my own tool into galaxy on a local instance. My galaxy UI is designed such that when a user selects Tophat only then can he choose cufflinks and if cufflinks is true only then can a user select cufflinks annotation (a classic use case of <conditional> statement).

I get a "ValueError: ('No case matched value:', 'turn_on_cufflinks', [u'yestophat']) " error with the xml code I used. Will highly appreciate it if someone could make me understand why this error occurs and any ideas on how to correct it.

Here is a piece of xml file that I wrote to do the above mentioned:

<tool id="rnaseq_pipeline_test" name="rnaseq_pipeline">
<description>Running RNASEQ Pipeline</description>

#if str($sample_file) != "": -s "$sample_file"
 #end if
#if str($genome_annotation) != "":
     -n "$genome_annotation"
 #end if
#if str($trimmomatic) == "yestrimmomatic":
#end if
#if str($tophat) == "yestophat":
 #end if
#if str($cufflinks) == "yescufflinks":
#end if
 #if str($cufflinksannotation) == "yescufflinksannotation":
#end if
#if str($rnaseqc) == "yesrnaseqc":
#end if
 #if str($rrnaquantitation) == "yesrrnaquantitation":
#end if
#if str($rsem) == "yesrsem":
#end if
#if $threads > 1:
    -e "$threads"
#end if
#if $max_process > 1:
    -j "$max_process"
#end if
 #if $output_directory:
#end if
<param name= "sample_file" type="data" value="samples.txt" format="tabular" label="Sample File:"/>

                    <option value="yestophat" selected="true">TRUE</option>
            <when value = "yestophat">
                      <conditional name="turn_on_cufflinks_annotation">

                                 <param name= "cufflinksannotation" type="select" label="Cufflinks Annotation" display="checkboxes" multiple="true">
                                            <option value="yescufflinksannotation">TRUE</option>


Thank you

I don't see a problem at a first look. I assume the error happens in the command line tag. It is probably best to show the complete xml file

I have edited my original post to include the entire xml file at this point. Let me know if you find error in the way the command line is constructed.

unless, this is a new feature I am not yet aware of, I would write

#if $turn_on_cufflinks.tophat == "yestophat":


instead of:

#if str($tophat) == "yestophat":


Hope this helps, Hans-Rudolf
