dear all, I have been trying to use the adj means/fmri button to collapse my fmri data with the intention of using the summary data in a second level analysis. However, as usual, i could not figure out how to do this! i am asked for the epoch order within the session.. which is OK. let us say i have 5 conditions within a sessions such that RACBRDCER where R is rest A, B, D, E are task blocks and C is another base line. For each block I have 6 functional volumes. I get in to trouble when I start filling in the number of volumes per condition.. it goes on and on and on... how come? Can somebody please spend a little time and explain to me how to do this properly? Thanks a lot, Priyantha Herath MBBS Div. Of Human Brain Research, Dept.
