repeating calculations

How do you realize repeating calculations with little variation. For example you have to build the ratio of every two neighbord columns (c3/c4 and c5/c6 and c7/c8) and so on. In the moment I use math formular one after another x-times. Very inconvenience.

Hi Werner,

you have two options, either use the same nodes more often. Or you use one of the Scripting nodes for this. e.g. Java/R/Python.

You could solve it using loops as well, but this would make the workflow pretty complex.

How many such columns do you have? And how is the data created and read into knime, is this one single file before as well?

Best regards, Iris
