list:list (as well as list:list:paired, list:list:list, etc...) can be created via the API or using tools. As an example of the second - if you had a tool that took in a dataset and split it into a list and then mapped a list over that tool - Galaxy would produce a list:list output from the individual jobs. (Explicit framework level support for grouping a list into a list:list almost made it into 16.01 - https://github.com/galaxyproject/galaxy/pull/1313 but didn't quite make the cut, hopefully it will be in 16.04). Tools can also explicitly produce nested collections such as lists of lists as of PR #538 (https://github.com/galaxyproject/galaxy/pull/538). There is however no current GUI or widget support for taking a bunch of datasets and building a list of lists from them. There was some discussion on this issue https://github.com/galaxyproject/galaxy/issues/1312 about adding such a thing. The builder for a list of pairs is pretty awesome - I imagine a list of list builder would be a whole new and distinct challenge unfortunately. -John On Wed, Jan 20, 2016 at 4:43 PM, Anmol Hemrom <anmol.jh@gmail.com> wrote:
Hi,
I was wondering if creating data collection of collection_type="list:list" is possible? Because I can see only list, pair and list of pairs options available.
Why I am asking this question is because I saw this snippet from cuffdiff tool which includes collection_type="list:list" as below.
<when value="CONDITION_REPLICATE_LIST"> <param name="conditions" title="List of Conditions" type="data_collection" collection_type="list:list" /> </when>
Thanks
Anmol
