Hi Cristel,

can you share some code. If you use discover_datasets like this,
format="" should indeed work.

<discover_datasets pattern=".*?\.(?P&lt;designation&gt;.*)\.sharedotus"
format="tabular"/>

Another feature is that the filetype is extracted from the extension if
you use it like this:

https://github.com/bgruening/galaxytools/blob/master/tools/text_processing/split_file_on_column/split_file_on_column.xml

Ciao,
Bjoern
