Dear folks,

I tried conducintg a DCM anlysis as explained in the sample data set attention.zip (http://www.fil.ion.ucl.ac.uk/~wpenny/datasets/attention.html) and following the steps in the attached read me.

However after I specified the model and load the file DCM_VisFroPar.mat to review I get an error message in matlab:

??? Reference to non-existent field 'M'.

Error in ==> spm_dcm_ui at 329

m = DCM.M.m;

??? Error using ==> pause

Error while evaluating uicontrol Callback.

The same error occured when I used the file DCM_VisFroPar.mat which is provided as a reference example in the archive http://www.fil.ion.ucl.ac.uk/~wpenny/datasets/glm_dcm_analysis.zip

I used Matlab 7.0 and SPM 2. Might there be any version conflict? Do you have an idea where the problem comes from?

Thanks for help
