Hi,

I am trying to publish message into some ROS topic using robotics system toolbox. However, I am getting the following error:

MATLAB System block 'rg_neuron/Publish/SinkBlock' error occurred when invoking 'setupImpl' method of 'robotics.slros.internal.block.Publisher'. The error was thrown from '
 '/usr/local/MATLAB/R2015b/toolbox/robotics/robotsimulink/robotslros/+robotics/+slros/+internal/+block/Publisher.p' at line 0'.
Caused by:
Error creating the node /rg_neuron_91338.

Please can somebody help me to fix this issue, or at least point me in the right direction? It will be greatly appreciated.

Thank you, Ben

I resolved the problem by connecting to the external master node and connecting to it through rosinit. I thought it might be helpful for someone in the future.
