Hi Daniel,
My apologies! I misunderstood what your question was about.
You are correct, the required inputs are defined when the workflow is
created. For tools that accept a variable number of inputs, when that
tool is added to a workflow, the run-time parameters, including expected
inputs, are defined.
Did you have a particular tool in mind? We can ask Dannon for some
suggestions/comments if you want to share your ideas about how this sort
of processing would flow.
I am glad you wrote back. Please send more details if you want and we
can try to offer more (better!) help,
Best,
Jen

Hi Jennifer,
Thanks for the reply.
However, my question was not about building tools.
My question was about building a workflow (using the workflow editor
with existing tools), as a user of galaxy.
Using the workflow editor, when I create a workflow using a tool that
allows a variable number of inputs, it seems that I have to define the
number of inputs during workflow creation and not when I run the
workflow.
I was just asking if it would be feasible to have a variable number of
inputs (only defined when a running instance of a workflow is created).
It feels to me that the answer is no.
Thanks again,
Daniel

Hello Daniel,
Examining existing tools that have multiple/optional inputs can be a
good way to see how this is done. One example is the tool: "NGS: QC
and manipulation -> Manipulate FASTQ".
The 'Manipulate FASTQ' tool source is here:
http://bitbucket.org/galaxy/galaxy-central/src/e58a87c91bc4/tools/fastq/
fastq_manipulation.py
fastq_manipulation.xml
The tool tag set is defined in this wiki;
http://wiki.g2.bx.psu.edu/Admin/Tools/Tool%20Config%20Syntax
See<repeat>,<conditional>, and<when> for more details and examples.
Questions about tools are best sent to the galaxy-...@bx.psu.edu
mailing list (the galaxy-user list is primarily for questions about
data/tools usages on the main public instance). I am going to forward
your question over there so that the development community can add to
my reply in case they have a simpler way of doing this or other advice.
Best,

Hi,
I wanted to build a workflow where the first step would be a tool that
can have a variable number of inputs (e.g. a series).
It seems that I need to predefine apriori the number of inputs to give
to the tool.
Is there a way to define the number of inputs at runtime?
E.g. a series-like input?
Thanks,
Daniel
