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> On Wed, Jul 16, 2014 at 6:54 PM, Peter Cock <p.j.a.cock@googlemail.com> wrote:

Hello to everybody

I'm developing my own tool that need to switch the numbers of output files according to a parameter selected by the user from a list in the <inputs> tag. How can I do such thing?

Here is the XML code: <inputs> <param name="input_dataset" label="Input dataset" 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-svm-dataset" Format</option> <option value="showelab" selected="True">".showelab-dataset" Format</option> </param> <when value="fbk"> <param name="input_fbk_dataset_labels" label="Input dataset labels" type="data" format="fbk-labels"/> </when> </conditional>

</inputs> <outputs> <data format="showelab-dataset" name="trainingDataset" label="Training Dataset extracted from ${input_dataset.name}"> <filter>format_options == "showelab"</filter> </data> <data format="showelab-dataset" name="validationDataset" label="Validation Dataset extracted from ${input_dataset.name}"> <filter>format_options == "showelab"</filter> </data> <data format="fbk-svm-dataset" name="trainingDataset" label="Training Dataset extracted from ${input_dataset.name}"> <filter>format_options == "fbk"</filter> </data> <data format="fbk-labels" name="trainingLabels" label="Training Dataset Labels extracted from ${input_fbk_dataset_labels.name}"> <filter>format_options == "fbk"</filter> </data> <data format="fbk-svm-dataset" name="validationDataset" label="Validation Dataset extracted from ${input_dataset.name}"> <filter>format_options == "fbk"</filter> </data> <data format="fbk-labels" name="validationLabels" label="Validation Dataset Labels extracted from ${input_fbk_dataset_labels.name}"> <filter>format_options == "fbk"</filter> </data>

</outputs>

Basically I would like to have in the Workflow Canvas that the outputs displayed in the interface will change according to the format_options select parameter.

Thanks in advance.

Hi Calogero,

I think this tool of mine would serve as a working example: https://github.com/peterjc/pico_galaxy/tree/master/tools/seq_filter_by_id

Ok, thanks for the the tip. I changed the XML to this one: <outputs> <data format="showelab-dataset" name="trainingDataset" label="Training Dataset extracted from ${input_dataset.name}"> <change_format> <when input="format_options" value="fbk" format="fbk-svm-dataset"/> </change_format> </data> <data format="showelab-dataset" name="validationDataset" label="Validation Dataset extracted from ${input_dataset.name}"> <change_format> <when input="format_options" value="fbk" format="fbk-svm-dataset"/> </change_format> </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-labels" name="validationLabels" label="Validation Dataset Labels extracted from ${input_fbk_dataset_labels.name}"> <filter>format_condition['format_options'] == "fbk"</filter> </data> </outputs> Still is not working, maybe the "<when input="format_options" value="fbk" format="fbk-svm-dataset"/>" . Maybe it has some problem since the "format_options" parameter is inside a "conditional" tag? Thanks a lot for your time.

You appear to have multiple defined datasets (three versions of trainingDataset) which may be the problem, as the name is meant to be unique.

I think you should have ONE <data> tag for trainingDataset but set this up to switch output formats accordingly.
