I have a workflow which works well. I read all the file in a directory and for each of these I do some operation. At the end, resulting outputs, have all the same strctures but they differ in the data. I’d like to concatenate all outputs in only one. How I can do that?
Hi @TommasoPalomba1 , welcome to the KNIME forum.
It’s difficult to work out exactly what your workflow is doing from just looking at an image, with no information about configuration.
However, in general, if you place your File Reader(s) inside the loop, and process each file within the loop, then the resultant output of the loop would be the concatenated results of all the processed files.
Typically for that, you would place a List Files/Folders prior to the loop, then iterate the returned paths from that with a Table Row to Variable Loop Start, and have each path passed within the loop to the File Reader and perform your processing.
