Hi Ed,
I tried your provided xml file, and your provided change_format tag worked to change the output datatype from fasta to qual454 when intype.sel is set to Qual454. It is worth noting that support of grouping constructs (including conditionals) was added in changeset 3472:bfcf6a3249c7 (beginning of March), so you may need to update your Galaxy source code.
There was a separate bug concerning the use of repeat grouping constructs and change_format tags or output data label templates in a tool causing a server error (e.g. 'TypeError: <galaxy.tools.SelectToolParameterWrapper object at 0x5f105d0> is not JSON serializable') which has been fixed in changeset 3609:23fb19105d96 that would affect your tool when a 'Filter' element was declared. Let us know if you encounter further issues when using the latest revision.
Thanks for using Galaxy,
Dan

hi, how do i reference conditional variables from within the change_format tag? i couldn't find any examples that did this. an example tool config xml file follows. thanks! ed kirton us doe jgi

**What it does**
Produces a Fasta/Qual file of selected sequences.
If the files are cosorted, a much faster algorithm is used. If it fails, it assumes the files were not cosorted and automatically tries again using the slower algorithm which does not require cosorted files.
One or more filters may be included to evaluate text (equal, not equal, contains, starts with) or numeric data (==, !=, >, <).
