Hi Vladimir, Thank you for your answer. I made sure SPM is on top of my path. I launched SPM as well to make sure the subfolders and private folders were on the path. I can epoch if I use the batch. However I want to write to my own code to do it. I have copied most of the SPM code and it seems that the built-in functions overload most of the MEEG methods. I am only able to use the methods with the form D.method, but cannot do method(D). Methods like fname(D) return this error: Error using subsindex Function 'subsindex' is not defined for values of class 'meeg' which subsindex built-in (C:\Program Files\MATLAB\R2014b\toolbox\matlab\ops\subsindex) I just updated SPM12. I have Matlab 2014b under Windows 7 enterprise 64b. Why would this work fine when launching from the batch but not when doing it myself? D.events(1,evtspm) works fine, D.fname as well. Thank you!
