Dear Tom, > I was just wondering if you had made any headway on the 2D > correction or if you could help me to make the necessary changes myself. Sorry, I thought the issue was resolved. For 2D-maps, the correction of p-values for peak height should work out fine. Correction of p-values for cluster size will be correct, if you change line 157 in spm_list.m to v2r = 1/prod(FWHM(~isinf(FWHM))); %-voxels to resels Stefan -- Stefan Kiebel Functional Imaging Laboratory Wellcome Dept. of Cognitive Neurology 12 Queen Square WC1N 3BG London, UK Tel.: +44-(0)20-7833-7478 FAX : -7813-1420 email: [log in to unmask] %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
