Hi, I am wondering how to handle optional arguments in a tool wrapper for Galaxy. I looked at other wrappers but could not find the way to do the right thing.

I don't think it works, see: https://bitbucket.org/galaxy/galaxy-central/issue/403 My patch may still work - I haven't looked at this recently though. Peter

Florent, you should be able to do this using cheetah scripting. Perhaps you can give the seed a specific (nonsense) default value like 0 or -1? You could check on this with cheetah scripting for this value and if so issue the command without additional parameters, otherwise issue the command witht the set values.... hope this helps and was your question.. lex ________________________________________ Van: galaxy-user-bounces@lists.bx.psu.edu [galaxy-user- bounces@lists.bx.psu.edu] namens Florent Angly [florent.angly@gmail.com] Verzonden: zondag 13 februari 2011 9:13 Aan: galaxy-user@lists.bx.psu.edu Onderwerp: [galaxy-user] Optional tool arguments Hi, I am wondering how to handle optional arguments in a tool wrapper for Galaxy.

Dear all, I am analyzing a set of miRNA-SEQ data. Many of the reads can be mapped to multiple locations. I want to test two options: divide the counts equally among all possible locations or randomly assign them to one of the the locations. Could anybody please let me know how I can accomplish this? Thanks in advance, JF

Thanks for the help Alex! I got it working this way: In the <inputs> section: <param name="random_seed" type="integer" value="0" optional="true" label="Random seed" help="Seed number to use for the pseudo-random number generator."/> In the <command> section: #if $random_seed > 0 -random_seed $random_seed #end if Florent

Does that actually let the user put an empty string in? My guess is not, and you are just using zero as the default (meaning no seed). This is the same workaround I have been using (where there is a suitable dummy values - not always the case). Peter

Yes, it simply is a workaround that allows me to keep working with Galaxy. Hopefully, your patch that fixes this issue can be accepted soon: https://bitbucket.org/galaxy/galaxy-central/issue/403/enhance-tool- parameters-to-be-optional Best, Florent
