Get Images from SiLA2 Server and Send Back Results

This workflow demonstrates how to get raw images from a (custom) SiLA2 server, how to process the data with KNIME nodes, and how to send comuptation results back to the SiLA2 server.

**IMPORTANT**
This workflow requires a Java library that we have not bundled to keep the file size minimal. Please import the entire SiLA Prototype workflow group (see link below) to run this workflow.

**IMPORTANT**
In order to successfully run this workflow, you have to setup a custom SiLA2 server. Please follow these instructions to start it:

1. Make sure that you have at least Java 8 installed on your computer and that the according environment variables are correctly set. (You can check this in a terminal by executing “java -version”)

2. Open a terminal or commandline and execute the following command: “java -jar <path to sila-server.jar> server -p 50052 -xml <path to plate.xml> -data <path to images.zip>”. (You can figure out the paths by right clicking on the respective item in the KNIME Explorer and selecting Copy Location > Local path)

3. Make sure that you see some output like "2021-01-08 12:37:31 INFO s.l.s.SiLAServer:97 - Server started on port=50052" in the terminal.
