publisheronly.slx

I'm having the same error. I attached my model.

p.s.: first time, I initialized roscore on ubuntu, then on matlab. I got this error.

second time, I restarted my computer and this time initialized ros on matlab. Still the same error.

I solved it by going to matlab script and changing the folder directory to the folder where the python code of my publisher node exists. I got this idea from below link:

https://forums.ni.com/t5/LabVIEW/permission-denied-error-when-using-Matlab-script/td-p/3209865

p.s.: I got this error in Simulink of a ROS publisher block. I had defined a publisher node in ROS before running this simulink block.

Based on the error message, you are running the model where you do not have write permissions. Please run the simulink model where you have write permissions.

Thanks,
