Jeremy, thanks! That is a great addition! Keep the logs out-of-sight of "normal" users that do not care. It is only blurring their history.... :-) Alex ________________________________ Van: Jeremy Goecks [jeremy.goecks@emory.edu] Verzonden: maandag 19 december 2011 19:51 Aan: galaxy-dev@lists.bx.psu.edu; Bossers, Alex Onderwerp: re: Hidden history item Alex, I just implemented this functionality in galaxy-central changset 303741fda0ec and documented it on the wiki. https://bitbucket.org/galaxy/galaxy-central/changeset/303741fda0ec http://wiki.g2.bx.psu.edu/Admin/Tools/Tool%20Config%20Syntax#A.3Coutputs.3E_... Best, J. Hi all, by default I let my tools produce ("the old way") a logfile of the console and additional running statistics. This is convenient at tool setup and ocassionally for troubleshooting. Anyway I would like to make the corresponding history item hidden. I tried including hidden="true" in the output tag but that does not make any difference. Is this possible at all or only applicable to running workflows? Any pointers appreciated. Alex
