I'm having some problems inputting confound EVs to my 1st-level FEAT analysis.  I have a text file, 2 columns, 144 timepoints with the timecourse for white matter and for CSF.  I created the file in Excel and then copied into plain text format TextEdit.  However whenever I try to run the FEAT GLM I get the error "Problem with processing the model: terminate called throwing an exception".  Any ideas?  I don't believe there are any hidden characters since it was created in TextEdit.

Thanks,

Daniel
