External Email - Use Caution Hi Bruce,
Thanks. I found a command from a previous post which seems capable of generating a surface data file in which all the vertices = 0 except the peak vertex: mri_volsynth --temp $SUBJECTS_DIR/yoursubject/surf/lh.curv --pdf delta --delta-crsf vertexno 0 0 0 --o delta.mgh I could run this command but I am not clear how to change the vertexno, what the three zeros denotes? If the index of my vertex is 1500 in fsaverage, how should I change above command accordingly? In addition, what are the meanings of flag "--pdf" and "delta"? I did not found the description in the "mri_volsynthn". Best regards, Lizhi
