I'm attempting to run SPM8 in Matlab R2008b on a Mac Intel under 10.4.11. However, Matlab crashes with spm_slice_vol.mexmaci dated May 29, 2009 (latest update). When I substitute the OLD version of spm_slice_vol_mexmaci, dated March 26, 2007, it runs fine. Are the updated mexmaci files not compatible with Intel running Tiger on a Mac? Is there another problem that I'm not noticing? Thanks so much for the help. Best, Michael Michael L. Spezio
