"Loop Subset Attributes: Feature Names"

Dear all,
I am working with the Loop Subset Operator to iteratively select exactly 2 attributes from my dataset and generate various new attributes based on these two, like atts1/atts2 or atts1*log(atts2). The thing is I would therefore need to address both attributes from a variable name.
If I only have one I can use Loop Attributes and set a variable name for that. But I would like to do this for two attributes. Is that possible?
Best regards,
Markus

Greets Markus,
You could nest loops, but that would create duplicate pairs, so you'd need to loop through the inner subset, like this ...<?xml version="1.0" encoding="UTF-8" standalone="no"?>
Or we can be a bit more fancy like this... 8)

I used this method to find functions in a myExperiment offering of that name. http://www.myexperiment.org/workflows/1321.html
