this threads has been inactive for quite a long while. However, I'd like to restart
There are two alternatives for improving the usability of the repeat tag.
1) If the repeat tag arguments could be populated using white pages and a filter similar
to the possibility for workflow, the user would be able to add several inputs at once.
2) If workflows would allow for using multiple (but not fixed number of) inputs obtained
via white pages as input of a repeat tag argument of a tool, the user could use the
functionality of multiple inputs (white pages) in workflows.
I would vote for the second proposal as it allows for building workflows with variable
number of inputs (e.g. read mapping and combined SNP calling for a variable number of
samples). Workflows with variable number of inputs have been brought up from time to time
at several posts or meetings. Hence, solving this could be hitting 2 birds with one
However, proposal 2 has the drawback that using repeat tag arguments outside of workflows
is still a lot of manual work.
This could be circumvented by tiny workflows consisting only of the tool of interest
(containing the repeat tag argument).
