Hi All - I am new to using SPM8 and have run into an error that I cannot figure out. I am trying to create 1st level contrasts. The same model was implemented for each participant, and for the first participant we were able to create the contrasts we needed without any problems. For other participants we can open the spm.mat file, and enter the contrast values we want, but before we can get the results we get an error.
So, to be clear, we go to "results" and open the spm.mat file. (Everything looks fine.) We enter the contrast values and click done. (This works as well.). We then click no for mask and hit enter when the name field comes up, then the error occurs. I have pasted the error below.
Again, the first participant was processed in the same way and it is working fine. Can anyone help?!? I have searched the forum but cannot find this same issue.
Thanks in advance!! Any help would be much appreciated!
Melanie
