Hi, We have a group of subjects where each has several contrasts that we're interested in (say A, B, and C). A 1-sample t-test shows that each of these contrasts activates a similar area. We'd like to do a conjunction analysis on each subject (so conjunction of A,B, and C) to get the areas activated in each contrast (we've got the conjunction updates in place and would be doing a conjunction test, not a global test). Then we'd like to use these results in another 1-sample t-test to see the significance of the group. Several questions... 1) Is this a valid method (doing single subject conjunctions, then combining them at the RFX level)? Most of the talk I see on the board talks about doing conjunctions between different groups, but we're interested in the different contrasts within the group. 2) If this is valid, how would I go about saving the results of the single subject conjunction so that I could use it at the 2nd level? Right now it seems I can just perform a conjunction while looking at results, but I can't actually save a con image to use later. Thanks -Mike
