Dear SPM I often have to do further computations on random effect analysis, such as for instance combining the results of two different tasks (e.g. motor and visual tasks) to look for overlaps. I do this by doing two separate rfx analysis, which create me their own spmT maps. Then using image calc, I do i1.*(i2>3.11), which gives me the T values of the first RFX but only in voxels where the other task was significant as well. Not to report that in a paper, its nice to have a table. In SPM99 I handled that by creating a bogus contrast in the first RFX, look at it, and then rename my image calc image as spmT003.img/hdr. Then visualizing my bogus contrast, I saw my image calc SPMT, and could visualise a nice results table. In SPM2 that doesn't work anymore, because of the header info's etc which are different. Any idea how to get a table from an image calc T map?
