External Email - Use Caution Hi Douglas,
Thank you very much! Could you please help me with more detailed information? 1) Should I use "Variables age" or "Variables age weight" in the fsgd file? If I can use either of them, which one is better? 2) For the contrast file, the content "1 -1 0" you mentioned, it corresponds to the "Variables age" fsgd file, correct? 3) If I use the "Variables age weight" fsgd file, what will be the content of the contrast file? Is it "1 -1 0 0"? Thank you again! Xiao
