Hi Tom,

Thanks a million for your reply.  Actually, I found out the problem.  I had renamed Stattalk.m script, which I downloaded some years ago, to g.m.   I also had modified the script so that I could select multiple subjects (peak voxel values at certain MNI coordinates).  Indeed, as you say, I realized that there was a confusion a few days ago.  So, I deleted the script and the problem is gone now.  YOU ARE QUITE RIGHT!  Now, SnPM works marvelously.

Again, I appreciate your reply.

Best regards,
Shary

Sorry you've had trouble.  We've tried to reproduce your problem
and haven't been able to.  I do have a few ideas, though:

        1. If you haven't already, please start with a 'clean
            slate'.  Start with an empty directory and make
            sure you're using a fresh downloaded copy of SnPM.
            When starting, make sure there are no errors current;
            (you can make sure of this by hitting Ctrl-C several
            times).      

        2. Check for other programs in your path.  In one of your
            emails I saw the error

                 ??? Attempt to execute SCRIPT g as a function.

                 Error in ==> c:\spm\spm2\snpm2\snpm_cp.m
                 On line 183  ==> if size(CONT,2) ~= size([H C B G],2)
        
            this suggests that you have a script g.m in your path
            somewhere, and Matlab is getting confused with it and
            the variable name G.


Please let me know how it goes.

-Tom
