Dear all, For example I got 100 subjects and several contrasts. At 2nd level analysis I tried to copy and paste all relevant con*.img/hdr collectively into a new folder. But it says error at running specifying 2nd level. Is there a way to quickly allow me to pick up files I want in spm specify 2nd level? Filter button works only when I'm into daughter folder containing the data, doesn't work when I'm in parent folder. Yours, Andy
