I am trying to run SSM-PCA toolbox using SPM5; however, I am running into several problems: (1) invalid mex files: spm_list_fls.dll and spm_w32utils.dll (I've copied them over from the SPM2 Update file), it still produced the errors about invalid mex-files. (2) Sometimes, the error messages go away; however, I get a prompt and output that says: "Get File Cancel". How can I resolve these issues and run the SSM-PCA toolbox. I am running Windows (32bit) with MATLAB2007a and SPM5.1782. Thanks. -- Best Regards, Donald McLaren ===================== D.G.
