Dear SPM Experts, I use SPM5 for analyzing fMRI data obtained with 72 volumes from a subject. In my experiment, there are three blocks which are fixation, novel, and repeat. After the "fMRI model specification" step, I get the following error message during the "Model estimation" step. Please help me solve the error. *Warning Dialog: No inmask voxels: empty analysis* MATLAB WINDOW: Running "Model estimation" SPM5: spm_spm (v$Rev: 946 $) 09:56:08 - 15/04/2010 ======================================================================= Initialising parameters : ...done Plane 1/69 , block 1/5 : ...read & mask data Plane 1/69 , block 2/5 : ...read & mask data Plane 1/69 , block 3/5 : ...read & mask data Plane 1/69 , block 4/5 : ...read & mask data Plane 1/69 , block 5/5 : ...done ..................................
