Crazy,what I warryed about ,what happened. 
error in ps_plot(‘w’),etc.
but ps_plot(‘u’) runs???
Soveled casually ,just becaue of my careless typing SBC case ‘ instead of DBC case of ’ ,It waste of nearly two hours .after all ,it run again 
yes, that’s tricky - matlab needs '' not ´´
Good luck with the further analysis
Hello @ABraun I had some problems running ps_plot(‘w’).This is after I run (1,1) and I had previously added the PATCH path to MATLAB.
