Hello Peter,

Thanks for your answer.

I tried your come but I am still not able to make it work the way I want.
I mean that in the workflow design page, when I switch the parameter, it
doesn't change the graphical list of outputs of the tool. How can I fix it?
I want something like the Input, where it shows different outputs according
to the selected parameter from the select.

Here is the XML code:


    <inputs>
        <param name="input_dataset" label="Input dataset (ShoweLab or FBK
Format) to split" type="data" format="showelab-dataset,fbk-svm-dataset"/>
        <conditional name="format_condition">

            <param name="format_options" label="Choose the type of dataset
you want to split" type="select">
                <option value="fbk">FBK Format</option>
                <option value="showelab" selected="True">ShoweLab
Format</option>
            </param>
            <when value="fbk">
                <param name="input_fbk_dataset_labels" label="Input dataset
labels (FBK Format) to split" type="data" format="fbk-labels"/>
            </when>
            <when value="showelab" />
        </conditional>
        <param name="split_perc" label="Percentage of Training Set among
complete dataset" type="float" min="0.05" max="0.95" value="0.75"/>
    </inputs>
    <outputs>
        <data format="showelab-dataset" name="trainingDataset"
label="Training Dataset extracted from ${input_dataset.name}">
            <filter>format_condition["format_options"] ==
"showelab"</filter>
        </data>
        <data format="showelab-dataset" name="validationDataset"
label="Validation Dataset extracted from ${input_dataset.name}">
            <filter>format_condition["format_options"] ==
"showelab"</filter>
        </data>
        <data format="fbk-svm-dataset" name="trainingDataset"
label="Training Dataset extracted from ${input_dataset.name}">
            <filter>format_condition["format_options"]  == "fbk"</filter>
        </data>
        <data format="fbk-labels" name="trainingLabels" label="Training
Dataset Labels extracted from ${input_fbk_dataset_labels.name}">
            <filter>format_condition["format_options"]  == "fbk"</filter>
        </data>
        <data format="fbk-svm-dataset" name="validationDataset"
label="Validation Dataset extracted from ${input_dataset.name}">
            <filter>format_condition["format_options"]  == "fbk"</filter>
        </data>
        <data format="fbk-labels" name="validationLabels" label="Validation
Dataset Labels extracted from ${input_fbk_dataset_labels.name}">
            <filter>format_condition["format_options"]  == "fbk"</filter>
        </data>
    </outputs>
