Dear SPMers, I always get the following error message when I try to run an estimate & write batch using VBM8, SPM8 with Matlab R2006a on Windows: VBM8 $Rev: 338 $ Failed 'VBM8: Estimate & Write' Invalid MEX-file 'c:\spm8\toolbox\vbm8\upfirdn2dMex.mexw32': The specified procedure could not be found. .

In file "c:\spm8\toolbox\vbm8\cg_vbm8_run.m" (v331), function "cg_vbm8_run" at line 89. The following modules did not run: Failed: VBM8: Estimate & Write ??? Error using ==> cfg_message>issuemsg Job execution failed. The full log of this run can be found in MATLAB command window, starting with the lines (look for the line showing the exact #job as displayed in this error message) Can anyone point me towards a solution for this? I was wondering whether this is due to the Matlab version that I am using? Many thanks, Kathrin
