Hello All,
MATLAB 7 now checks the class of the string arguments for the sprintf function. SPM2 has not been updated to deal with this stricter type checking yet and will generate the the following warning (many, many times):
Warning: The argument for the %s format specifier must be of type char (a string).
Until the SPM2 maintainers fix this issue, you can supress this warning by typing the following:warning off MATLAB:sprintf:InputForPercentSIsNotOfClassChar
Enjoy,
Chuck
P.S. This suggestion also applies to MIPRead from the BIAC EEG Toolbox.
