No problem, I was not writing my question clearly... I suspect a pb with the stacks_summary related script... Can you investigate it, I unfortunately can't work on it for now. .. Maybe ""just"" a missing python interpreter invocation somewhere. .. when executing stacks_summary. ... -------- Message d'origine -------- De : David Meltzer <David.Meltzer@glasgow.ac.uk> Date : 07/07/2017 13:47 (GMT+01:00) À : Yvan Le Bras <yvan.le-bras@mnhn.fr>, galaxy-dev@lists.galaxyproject.org Objet : Re: [galaxy-dev] ustacks - bad interpreter Good afternoon, I apologize. I misunderstood the question. Yes, stacks_summary has been installed correctly as have stacks and velvet. Additionally, the tool is outputting three items into the history - Summary from Stacks – red (error) Ustacks.log – red (error) Stacks from Data – green (successful) Best Regards, David Jacob Meltzer From: galaxy-dev <galaxy-dev-bounces@lists.galaxyproject.org> on behalf of David Meltzer <David.Meltzer@glasgow.ac.uk> Date: Friday, July 7, 2017 at 12:31 PM To: Yvan Le Bras <yvan.le-bras@mnhn.fr>, "galaxy-dev@lists.galaxyproject.org" <galaxy-dev@lists.galaxyproject.org> Subject: Re: [galaxy-dev] ustacks - bad interpreter Good afternoon, I am sorry.

Can you check you have stacks_summary well installed ? I think it is but there is a pb using it...
