Hi, We preprocessed all EEG files using EEGLab then, try to run averaged file (.erp) in ERP PCA toolkit to separate certain ERP component from other components then, will pull out "pure" ERP component values from certain TF factor. To start this, I am trying to load grand-averaged erp files across all subjects (.erp) (see the attached). In "read" function, when I loaded the file, it says, ' defective file will not be loaded'. Would you please check the attached file? Q1. can I use grandaveraged file...

Hi, Joe, Great! Many thanks! As suggested, I tried to attach .ept file but can't attach it as it is too large. Can you let me know your email? Then, I can share the file with you. or email me at yusun.chung@duke.edu. I really appreciate your help!!

Hi, I ended up changing the 130th channel to "REG" in Edit function and ran PCA again. This time, I see that the 130th channel (i.e., pooling site) is not included in PCA analysis. Then, in the View, Topography function, I right clicked to check Jack knife option. but I face the same error that I had before.. At this point, I am stuck.. If you have any suggestions to fix this, would you please help me? Many thanks!

Hi, Joe, so, I tried to use "Edit" function as suggested but, when I changed "EEG to "REG" for the last 130th channel in the Edit, error pops up.. it seems like it doesn't read it correctly (see the attached) Do you think there might be better solution to fix this?

Hi, I tried to attach one subject's .dat and. vhdr files. Are there files what you are looking for? I wanted to attach .edf file but I couldn't. If you let me know your email address, I think that I can share .edf file with you through Duke Box. Just let me know!
