Hi! I have some p-peaks from a third level analysis I did. These peaks should be correlated to the dependent variables I have. I tried doing a mean of the variables and do a correlation in MATLAB, but I got Nan as a result, so I thought that this wasn't the correct approach. How would you do this? Thank you so much, Carlotta. ######################################################################## To unsubscribe from the FSL list, click the following link: https://www.jiscmail.ac.uk/cgi-bin/webadmin?SUBED1=FSL&A=1
