Hi Ross,

I agree, normally I use the label="" xml tag when possible, but the reason I ask this question is because I have a tool where the number of output datasets cannot be determined until the tool is run (a la https://bitbucket.org/galaxy/galaxy-central/wiki/ToolsMultipleOutput) and I really would like to change the dataset labels/names of what is produced.

Could you provide some insight as to how you get it to work with one of the hooks? You might have seen in another post I made yesterday, when I try even just a simple example using exec_before_job() I get some strange error :-/

thanks again, leandro

I used to use the post job hook but I think it's a lot cleaner to use the label option - eg where I want the output name based on a user supplied text string "out_prefix", something like:

<outputs> <data format="html" name="html_file" label="${out_prefix}.html"/> </outputs>

works for me and avoids the need to have a post execution hook code file.

Hi again,

Sorry that I didn't know before, it seems like the label is the the

attribute 'name' programmatically, but even if I set this in exec_before_job(), exec_before_process(), exec_after_process() it doesn't change the dataset name even after refreshing my history.

Has anyone had success setting dataset label/name and other attributes

using

one of the custom code hook functions??
