Multiport Loop End

Vernalis Flow Control extension for KNIME Workbench version 1.30.1.v202103301200 by Vernalis (R&D), UK

Node at the end of a loop. It is used to mark the end of a workflow loop and collects the intermediate results by row-wise concatenation of the incoming tables. The start of the loop is defined by the loop start node, in which you can define how often the loop should be executed (either fixed or derived from data, e.g. the "group loop start"). All nodes in between are executed that many times.

This node was developed by Vernalis Research . For feedback and more information, please contact knime@vernalis.com
