Hi, 

Thanks for using BrainNet Viewer. 

This error reports that it was caused by the function 'rotate'. It seems that some toolboxes you've installed in matlab include a function named 'rotate'. When BrainNet Viewer called the default 'rotate' of matlab, the installed one was used and caused the error. Please check your installed toolboxes and remove the duplicated 'rotate' function. 

Best,
Mingrui
