Hello, I am a beginner to Simulink! I am trying to add and delete lines on a simulink model. I am using the following two commands "add_line('Using_Common_Nodes','Resistor1/LConn1','Resistor3/LConn1')" and "delete_line('Using_Common_Nodes','Resistor2/RConn1','Resistor3/RConn1')". add_line command works fine but while using the delete command, the following error comes up "Invalid line specifier". The error appears whenever I try to delete a line that is connected to a node. Please help.

Command line interaction like this is not really a beginner thing. Silly question, but I assume you know you can just press the delete button on the keyboard with signal line selected?

I am working on an application that requires me to interface the Matlab GUI with Simulink. So essentially, i need to use command line arguments to delete the line. My application has the GUI as the front end with a simulink model running in the background.

Well your API calls are of the correct format so you must have a block name or port mismatch. I suggest you start by trying the delete_line command for the same set of blocks that you successfully connected with the add_line command just to give yourself confidence. After that you will need to check names. It's hard to say more without seeing your model.
