Concatenate result of looped step using json

[obushakv]

Hi. I need to concatenate results of looped (while, foreach) step
I've found the solution here
#308
...
.Output((step, data) => data.ClusteredORFS.AddRange(step.outputORFs))
...

Is it possible to do something similar using json workflow definition?

Thank You.

Ok, it is pretty easy.
"outputs" : {
"ClusteredORFS" : "getattr(data, 'ClusteredORFS', []) + [step.outputORFs]"
}
