Hi Alex, No, instead try: 1. "Filter and Sort -> Filter" - run twice 2. "Text Manipulation -> Add" - run twice 3. "Text Manipulation ->Concatinate" - run once 4. Optional: extract this method into a workflow (History menu), and save for future use - in effect creating your own custom tool. The workflow can even be saved onto the Tool Menu (on the Workflow home page, click on "Other options -> Configure your workflow menu" - is a nice short cut). Then sort, restore metadata, etc. as needed. Hopefully this helps, Jen Galaxy team On 11/7/13 11:29 AM, Leontovich, Alexey A., Ph.D. wrote:

Hello!

I have the same question as Ido Tamir had about a year ago:

/Dec 07, 2012; 9:53am //Ido Tamir/ <http://user.list.galaxyproject.org/template/NamlServlet.jtp?macro=user_nodes&user=317241>/Ido Tamir <http://user.list.galaxyproject.org/template/NamlServlet.jtp?macro=user_nodes&user=317241> conditional in Compute tool /

/Hi, is it possible to do a conditional in the compute tool? something like:

"a" if c1 == 4 else "b" or if c1 == 4 "a" else "b" or c1 == 4 ? "a" else "b"

thank you very much, ido /

Thank you very much,

Alex
