Hi, all: I am trying the Dartel in spm8b following the Dartel guide. I met some problems in the 1.2.1 step (affine transform of Dartel template to MNI space) The parameter I set is --Data *Subject Source Image: Template_6.nii Source Weighting Image: 0 file --Estimation Options * Template Image: apriori/grey.nii (??But from the John's introduction is tpm/grey.nii, which one should we choose here?) * Template Weighting Image: 0 file * Source Image Smooting: 8 mm * Template Image Smooting: 0 mm * Affine Regularisation: ICBM space template * Nonlinear Frequency Cutoff: Inf * Nonlinear Iterations: 0 *Nonlinear Regularisation: Inf However, when I run this step, the matlab report error as following Running 'Normalise: Estimate' Failed 'Normalise: Estimate' Cell contents reference from a non-cell array object. In file "C:\Program Files\MATLAB\R2008a\work\spm8b\config\spm_run_normalise_estimate.m" (v2312), function "spm_run_normalise_estimate" at line 27. The following modules did not run: Normalise: Estimate Does anyone know what's wrong with it? Thanks very much. Wei
