Thank you for the answer! I tried and no I don't have the --voxthresh option. Maybe it is because I have FSL 5.0.9? I wanted to have this, because I needed the p-peaks in the lmax file as they have in the article. Thank you again, Carlotta. ######################################################################## To unsubscribe from the FSL list, click the following link: https://www.jiscmail.ac.uk/cgi-bin/webadmin?SUBED1=FSL&A=1
